PhD Interview Questions and Answers

Written by Mark Bennett

Your PhD interview will be an important part of your postgraduate research application. This is your chance to meet your prospective department, discuss your project and show your potential as an academic researcher.

Of course, it’s also when that potential is going to be assessed.

You’ll need to show an awareness of what’s involved in a PhD project and prove that you have the right aspirations and approach to work on one for three (or more) years. You’ll also need to make it clear that this is the right university, department, research group or laboratory for you.

None of this has to be especially intimidating. Putting some thought into your project and your choice of institution can make answering PhD entrance interview questions quite simple.

On this page we’ve put together a list of the questions you might be asked at an interview. We’ve also explained why the university might be asking each question, and provided some tips on how to answer them

You won’t necessarily be asked all of these questions – and you almost certainly won’t be asked them in the order here. Some of them also overlap with each other. But they’re all topics that you should prepare to discuss at a PhD interview.

We’ve also included a selection of questions to ask during a PhD interview.

Interview questions about you

Your qualities as a researcher, team-member and individual are some of the most important factors in a university’s decision to accept you for a PhD.

Regardless of your subject area, you need to be the kind of person who can dedicate themselves to a three-year project. You also need to be able to work alongside other students and academics in a positive and successful research environment.

The interview is the best way for a university to assess this. Just as there’s more to doing a PhD than research and writing, there’s more to a prospective candidate than their academic record.

#1 Tell us about yourself…

This popular opener can feel like an awkwardly open ‘question’.

You’ll be prepared to explain your project, to say what a great fit it is for the university, perhaps even reference some current research. But how do you ‘answer’ an invitation to introduce yourself?

By introducing yourself.

Your interview panel isn’t trying to catch you out here. They’re offering an icebreaker to help ease you into the rest of the interview.

Obviously your response should be relevant to the occasion. But it doesn’t just have to be a presentation of your academic achievements, interests and goals (the interview will get to those in time!).

Say a little about your background, where you’re from and what your interests are. Don’t be afraid to relate these to your academic specialism and your choice of university.

If something specific inspired you to consider a PhD, mention it. If there’s something that’s attracted you to this city as well as the university, say so. (There’ll be plenty of time to talk up the institution and its research later).

Do answer:
  • I’ve always been interested in discovering how things work, but my time as an undergraduate opened my eyes to the excitement and wider benefit of science. I had the chance to do some original research on my Masters and that’s inspired me to take up the challenge of a PhD. I’m also a keen hiker and amateur naturalist, so I’d love to combine my studies here with the chance to visit the local area.
Don't answer:
  • I was born in a house next to the local post-office. My first cat was called Timothy and he liked chasing string. At school my best friend was Kevin. My favourite colour is blue and my favourite flavour of ice-cream is raspberry ripple…

#2 What made you choose to do a PhD?

At some point in your interview your interviewers are going to want to know why you decided to do a doctorate.

This may seem like a simple question, but be wary of giving an overly simplistic answer. Just pointing out that you’re good at your subject and a PhD seemed like the logical next step won’t be enough – especially if there’s a funding decision to be made.

The panel is already satisfied that you’re academically capable and interested. You’ve demonstrated that by getting an interview (and turning up for it).

Now they want to assure themselves that you’ve got the motivation and drive to see you through three or more years of hard work on a PhD project.

Do answer:
  • I’ve enjoyed my academic work so far, but I really feel I’ve got more to offer as an independent researcher. I’m also passionate about this subject and don’t feel enough attention has been paid to the questions I’m looking to address.
Don't answer:
  • I can’t think of anything to do with my Masters, but my current tutor says I’m clever enough for a PhD.

#3 What do you plan to do after you complete your PhD?

It might seem strange for your panel to ask about your post PhD plans. After all, those don’t have any really impact on your ability to do a PhD, do they? And graduation is at least three years away in any case; should you have thought that far ahead?

The answers to which are ‘yes’ and ‘of course you should.’

Universities want to make sure you’re doing a PhD for the right reasons (as above). Asking about your future plans is a great way to check this.

Students who ‘sleepwalk’ into a research project are much more likely to come unstuck or lose motivation when the going gets tough later on.

This doesn’t mean you have to have everything worked out, or that your ambitions have to be unique. If you're planning to apply for a post-doc after your PhD, say so. But demonstrate an understanding of academic career paths – and show that you’ve put some thought into alternatives.

It’s also the case that not everyone who gains a doctorate will go on to an academic job. Universities want to recruit PhD students responsibly and provide the kinds of skills and training they actually need.

So, don’t feel that you have to want to be a scholar to be accepted for a PhD. Research training can prepare you for a range of career paths. An appreciation of these will impress your interview panel. (Particularly if you’re applying for a professional doctorate).

Do answer:
  • I feel my PhD project can open up new lines of inquiry for this field and want to use it as the foundation for a fruitful research career. But, I’m also interested in the wider development opportunities included in this doctoral programme. I want to be an academic, but I’m happy to keep other options open.
Don't answer:
  • I expect someone will give me a job doing more research. That’s what PhDs do, right?

#4 What are your strengths and weaknesses?

A well-worn question, but a great opportunity to reflect on your abilities - as well as opportunities for further development during your PhD.

What your panel is really interested in is not so much what your strengths and weaknesses actually are, but your ability to identify them.

In practice, this means giving solid examples for strengths and showing how they relate to the PhD project you have in mind.

Don’t just say you’re a good time-keeper. Point out when you’ve had to be well organised and show that you understand the importance of self-directed study to a successful PhD.

When it comes to weaknesses, maintain the right balance.

A PhD interview probably isn’t the best time to wallow in existential self-doubt (unless you’re applying for a very specific topic in Philosophy). Equally though, answers like ‘my only downfall is excessive perfectionism’ can sound a bit contrived. If the panel is asking you about strengths and weaknesses, they want you to identify and reflect on both.

Be honest about the things you find challenging, but identify them as training needs and discuss how you expect to improve upon them as part of your PhD.

Do answer:
  • I feel that I’m a good written communicator. My existing academic and professional work demonstrates an ability to put forward ideas clearly and concisely. I think this will help me manage the weight of information my PhD research needs to cover and the challenge of producing an effective thesis. But, I’m not always as organised as I’d like to be. I want to address this as part of my postgraduate training and hope to take advantage of classes and development opportunities early in my doctorate.
Don't answer:
  • My greatest strength is that I have no weaknesses! And my only weakness is that I have no strengths. Hang on...

#5 Are there any training needs you can identify ahead of your PhD?

This question (and its answer) can be part of an invitation to reflect on your strengths and weaknesses (as above).

But, you may be asked about training needs more specifically. This is likely if you’re applying to a more structured programme, within a Doctoral Training Partnership or similar.

Either way, this is a great opportunity to reflect on your aspirations as a researcher and show that you’ve read up on the project you’re applying to. If the university offers a series of training modules, mention them. Say what you hope to gain from them and how you think they’ll help you succeed in your PhD.

You might also want to refer to any discussion of your aims and aspirations with a doctorate. If you’re keeping an open mind about non-academic career paths, show an awareness of the transferrable skills this PhD can give you.

And don’t worry about revealing a few gaps in the core skills required by your discipline. A PhD is a training process, not a three-year exam.

Do answer:
  • I’m really interested in communicating my research to a wider audience, but don’t know how best to go about doing this. I think the training module on public engagement will be a big help to me, both academically and more generally.
Don't answer:
  • I’m really bad at interviews. Do you have a class for that?

Interview questions about your PhD project

This is the university’s chance to further assess your suitability for an advertised PhD position, and the likely fit between your planned project and the expertise it has available.

It’s also your chance to expand on your research proposal and show that you have the skills, experience and understanding to complete a doctorate. For funded places (or other competitive projects), this is the time for you to prove that you are the best student for this PhD.

It’s a good idea to reference your research proposal (or other appropriate parts of your application) when answering these questions. But expand upon what the panel has already read. (And make sure there isn’t anything in that proposal that you aren’t confident enough to ‘back up’ in your interview!)

#6 Why this project?

The exact focus of this question will depend on whether you’re applying for an advertised PhD project (more common in Science, Engineering and Medicine) or proposing your own research within a department's PhD programme (more common in Arts, Humanities and some branches of the Social Sciences).

If you’re being considered for a pre-defined project, make sure you know it inside out. Say what it is that interests you about it. Compare it to similar projects (if appropriate) and explain your particular choice.

If you’re proposing your own project, this is your chance to show some passion and enthusiasm for it. Refer to your research proposal and take the opportunity to discuss and expand upon it.

In both cases you should point to some existing scholarship and show an awareness of the field you’ll be entering. You’ll also want to re-iterate what makes your project distinctive. After all, the PhD is defined as offering ‘an original contribution to knowledge.’

This doesn’t mean preparing a comprehensive list of key works or current research projects (that ‘literature review’ will be one of the first things you do on the actual PhD). At this stage the panel just wants to see that you understand your proposed project and are enthusiastic enough to see it through.

Depending on how the question is phrased, you may also discuss your choice of university at this stage – or explain why your previous work makes you a good fit for this particular PhD (see below).

Do answer:
  • This PhD appeals to my existing research interests. But I’m also attracted by the opportunity to specialise and develop new expertise. Other projects didn’t seem to offer the same possibilities to pursue the questions that really interest me.
Don't answer:
  • To be honest, I’ll do anything if it’s funded.

#7 What makes you the right candidate for this PhD?

If you’re applying for a pre-defined PhD project, you’ll almost certainly be asked why you are the best candidate to undertake it (especially if there’s funding available).

Remember too that some of these projects aren’t automatically funded. Their financing can depend on the quality of the student they attract, so your panel will be very keen to make sure you’re going to be ‘Dr Right’.

You might still be asked about your suitability for a self-proposed PhD (in Arts or Humanities, for example). This is another way for your interviewers to assess those all-important motivation and commitment factors.

Whatever your situation, this is a good place to talk a bit about your previous work at undergraduate or Masters level. The panel already knows the grades you received, but now you have the chance to talk about what you actually did on those degrees. Show passion and give examples.

If an undergraduate module on gothic literature inspired you to propose a PhD on an under-researched aspect of eighteenth-century culture, say so. If your Masters has given you skills in exactly the kind of statistical analysis required by this doctorate, mention that.

Do answer:
  • I’ve been interested in this topic since the final year of my undergraduate degree. This lead to my choice of Masters and helped me pick my dissertation topic, which I really enjoyed. I’m really excited to now go on and do some sustained research in this area as a PhD student.
Don't answer:
  • Well, I really like books…

#8 What difficulties do you expect to encounter during this project?

This is another fairly popular question topic. It might form part of a discussion of your strengths, weaknesses and training needs. Or you might be invited to speak more specifically about the challenges involved in your project.

The panel isn’t trying to catch you out here, so don’t be afraid to speak frankly. All projects involve their own potential pitfalls and complications.

Overcoming them will be part of completing a PhD; recognising them will show that you're ready to begin one.

Show that you’ve put some thought into the approach necessary for your research and the methodology you might use.

Don’t be afraid to identify problems you aren’t yet certain how to solve (the best way to organise some data, the authors to include in your initial survey of texts, etc) but suggest how you might go about investigating them.

This is also a good time to mention any training needs (if you haven’t already) and speak about how you plan to take advantage of development opportunities within your programme.

Do answer:
  • I can see that some of the archival material I’ll need to examine for this project may be difficult to access. My first task will be to request permissions, arrange visits and develop a system for recording my findings. I’m hoping to undertake training in archival practices and seek advice from my supervisor as I develop these key skills early in my project.
Don't answer:
  • Yeah, I know a PhD is hard, but I’m just going to see how I get on.

#9 What would you like the impact of this project to be?

‘Impact’ is an increasingly important factor in academic work and this applies to PhD research too – especially if you’re funded.

Even if your panel doesn’t explicitly ask about impact, it’s a good idea to mention what you hope the wider outcome of your project might be. If you are asked this question – and are prepared for it – this is a great chance to get a leg up on the competition.

Impact essentially refers to the measurable effects of research outside academia. It’s a given that your PhD will have an effect on future work in your field. But universities are increasingly focussed on the benefits of their work beyond the ‘ivory tower’ of higher education and research.

This is particularly important if your project is funded. The money supporting your studies will probably have come from public revenues (via a Research Council studentship) or from a large charity or trust. Those organisations will want to make sure their investment is worthwhile.

Examples of impact differ a bit between fields.

If you’re in the Social Sciences you may already have some idea of the ‘outputs’ from your project. These could be educational workshops, policy guidance, etc.

If you’re in Science, Medicine or Engineering you’ll hope to provide economic benefits to industry or to healthcare.

Arts and Humanities PhDs can have impact too. Think about the ways in which you could take part in public engagement, such as teaching people about local history or archival resources. You could partner with local schools, or even media companies producing documentary work.

Do answer:
  • I’m keen to share my passion for this subject with a wider audience. I’m hoping to maintain a public-facing blog documenting my research. I would also be keen to approach local schools and museums to discuss educational events.
Don't answer:
  • To be honest, I can’t really see how my work on medieval manuscript preservation has any benefit outside the university. I’d still like some funding though.

#10 How will you fund this project?

This question is obviously more likely in interviews for non-funded PhDs. (It would be somewhat strange for a university to ask you about funding for a project that carries a full studentship).

However, you might still be asked about contingency plans if funding falls through (particularly if funding hasn’t been secured at this stage) or if your project over-runs.

Self-funding students will obviously need to go into more detail here. It’s not the responsibility of your university to ask for a complete breakdown of your finances (or for you to provide one). Yet the panel will want to be sure that you understand the cost involved in doing a PhD and have some kind of plans in place.

It’s fine to say that you’ll be looking for extra funding and part-time work as you start the project. But make it clear that you’ll still have enough time to apply yourself to the actual research.

Do answer:
  • I’ve shortlisted external funders and would be keen to investigate any small bursaries or other forms of support through the university. I’ve also made arrangements to work part-time, with the option to adjust this if my funding situation improves.
Don't answer:
  • I have no idea how I’m going to afford this. Are you sure I can’t have a scholarship?

Interview questions about your choice of university

Unsurprisingly, your interview panel will be interested to know why you’ve chosen their university for your PhD.

If proposing your own project you’ll be asked about the fit between your research aims and the expertise of the department you’d be entering.

If applying to a pre-defined PhD, you’ll be invited to explain why this laboratory or research group particularly appeals to you and what you yourself can contribute to them.

Preparing for these kinds of questions is actually quite easy. Read up on your prospective university, department and supervisors. Show that you’re aware of the kind of work they do and give examples.

Feel free to mention other aspects of the university that appeal to you – its reputation, its alumni, even its location – but keep the main focus on the fit between your work and their research environment.

#11 Why have you chosen to study a PhD at this university?

Whatever else your panel asks, you can be pretty sure a question about your choice of university and department will crop up at some point in a PhD interview.

Your answer gives you the opportunity to do several important things.

Most obviously you can talk about the university and its research. Explain why you’d like to study with these supervisors in particular, when you’ve used their work during your Bachelors degree or Masters (if relevant) and how you can contribute to their future projects.

This is also an opportunity to reiterate your awareness of the wider research context for your project. If other departments or laboratories are undertaking related work, mention that. Say what attracted you to this university in particular and what you hope to achieve as one of its students.

If your PhD is part of a structured Doctoral Programme (as is increasingly likely) you can touch on any training and development opportunities it includes. You may mention these elsewhere in your interview, but make sure to include them when speaking about the university’s appeal to you.

Finally, show an awareness of any relevant research facilities, resources or collections.

Does the university hold a unique archive? Suggest how it might support your investigations. Has the laboratory you’re working in been equipped with any new facilities? Show that you know about them and are interested in using them (as relevant).

Universities spend a lot of money on facilities and resources. They want students – particularly postgraduate researchers – who will make use of them.

Do answer:
  • I’ve looked at lots of opportunities in this area. I feel that this project is the best of its kind, combining a unique research angle with a training programme that will meet my professional needs. I was already familiar with the work of my prospective supervisor and their research has greatly informed my own development as a scholar. I’m eager to combine my work with theirs and make use of the facilities the university has put together for this project.
Don't answer:
  • I did my Masters here and already have a flat in the city.

#12 What can you bring to this research group?

PhD candidates are more than just students. You’ll function, in many ways, as a junior academic working within a wider research environment.

You’ll network with other students and academics. You’ll probably teach undergraduates. You may even publish some of your research (independently, or alongside your supervisor).

This means that your potential contribution to a department or laboratory is, in many ways, just as important as what it can offer you.

If you’re asked a question about this, take the opportunity to sell yourself a little.

Talk about your experience (academic or professional) and outline your ambitions. Make it clear that you will provide a return on the time, money and resources that the university is considering investing in you.

Do answer:
  • I’m eager to take advantage of the facilities and expertise this university has to offer. But I also want to contribute with my own expertise and enthusiasm. My previous work has given me the skills to make the most of the material involved in this project and I’m motivated to participate in new training. I’ll be proud to be a part of this department and would actively seek to represent it through my own publications and other research outputs.
Don't answer:
  • I have a Bachelors and a Masters in this subject so I’m quite clever.

What to ask in a PhD interview

Your PhD entrance interview will probably end with an invitation for you to ask your own questions of the panel. This part of the interview is as important as the answers you'll have already given.

Asking good questions demonstrates your motivation. It also shows that you’ve given some genuine consideration to the project and / or programme you’re applying to.

Don’t just ask questions ‘for effect’ though. This is your chance to find out more about the project you’ll be doing, the people you’ll be working with and the expectations of you as a PhD student.

Remember: you’re a good student, with lots of potential. You’re considering at least three years of hard work with this university. You need to know that you’ll get on with your supervisor, that your work will be appreciated and that there are good prospects for your project.

You’re here to be interviewed for a PhD, but nothing’s stopping you from doing a little interviewing of your own.

Here are a few good questions to considering asking at your PhD interview. They include ways to express enthusiasm for your project, as well as some useful inquiries to make for yourself:

What will the supervision arrangements be for the project?

This shows that you’re thinking practically and looking ahead to the process of actually doing the PhD. It’s also something you’ll probably want to check for yourself.

What kind of training and skills sessions are offered as part of the PhD programme?

This shows that you’re interested in the development opportunities that form part of a modern PhD. It’s also a good way to address any concerns you have about your own skills. Be careful though. Avoid asking simple questions about material that’s already covered in the PhD project description, or in the university’s postgraduate prospectus.

Will I have opportunities to teach / present / publish?

This is something else you’ll want to know for yourself, but it also demonstrates a practical approach to your PhD (and future career). A good PhD programme should offer some opportunity to teach or demonstrate towards the end of your project. Equally, you should be encouraged to communicate your research and supported in doing so.

How many other PhD students has this supervisor seen to completion?

Don’t be afraid to ask about previous students and what they’ve gone on to do. You may also want to know if you’ll be working with or alongside other students and what the arrangements for that will be.

Are there likely to be any changes to the funding arrangements for the project?

A good practical question. If you’re applying for a funded place, make sure you understand the terms of that funding (its duration, whether you can combine it with any other income, etc). If you’re currently self-funding, it won’t hurt to ask if the university anticipates having any support available for you in future.

Is the university or department likely to run any events or other associated projects during the period of my PhD?

This might not seem like an obvious question, but it’s worth asking. The university might be in the early stages of planning a major hosted conference, external partnership or outreach project. Asking about these shows a genuine interest in your university and its research and suggests that you’ll be the right sort of PhD student to help deliver them. Needless to say, these kinds of projects are also excellent opportunities to gain experience and build your CV.

Other questions will probably occur to you according to your specific circumstances and the nature of the project you’re applying to.

Focus on the things that would concern you as a student actually doing the PhD in question, but avoid trivial topics. Your panel will be happy to talk about library resources and lab facilities. They’ll be less keen to advise on the best local pubs or say how often the bus runs between campus and town.

Also try to avoid asking for information that’s readily available elsewhere. This suggests you haven’t done your research – which is never a good sign when applying to do research.

Still looking for that perfect PhD project?

While you're preparing for the interview stage of applications, it's a good idea to keep searching as many PhD projects are advertised throughout the year.
