PhD Student Interview Questions UK: 8 Real Questions and What Interviewers Want

Before your PhD Student interview, it helps to see the questions from the interviewer's side. We have picked eight from our set of 16 and added the reason each one gets asked.

Eight PhD Student interview questions, and what the interviewer is thinking

1. Why do you want to do a PhD, and why at this university and with this supervisor?

Why they ask: Panels need to see genuine motivation and a considered fit before committing funded years.

2. Can you summarise your research proposal in a couple of minutes and explain why it matters?

Why they ask: This is the opening question in almost every PhD interview and tests clarity and originality.

3. Why have you chosen this methodology, and what are its limitations?

Why they ask: Panels want evidence you can justify design choices and recognise weaknesses.

4. Six months into your project, your key experiments or data collection are not producing usable results. What do you do?

Why they ask: Research rarely goes to plan; resilience and judgement are essential.

5. How would you structure your three-and-a-half or four years, and what milestones would you work towards?

Why they ask: Panels want to see that you can plan and finish a large independent project.

6. What ethical issues does your research raise, and what approvals would you need?

Why they ask: Ethics approval is mandatory and a sign of research maturity.

7. How will you manage, store and share your data so that your research is reproducible?

Why they ask: Funders and universities increasingly require data management and open research practices.

8. Tell me about a time you planned and completed a substantial independent project, such as a dissertation.

Why they ask: Your ability to work independently is the best predictor of PhD completion.

A sample answer to question 1

Why do you want to do a PhD, and why at this university and with this supervisor?

I want to do a PhD because my undergraduate dissertation left me with questions that could not be answered in a few months, and I enjoyed the independence of designing and running a project. I see doctoral research as training to become an independent researcher, and I plan to pursue an academic or research-intensive career. I chose this university because the department has recognised strength in my area and access to facilities and datasets that my project needs. I have read my prospective supervisor's recent papers, in particular the work on longitudinal methods, and I think my proposal builds on it while adding a new angle. I also noticed the department's research group meets regularly and offers training through the doctoral training partnership, which will help me develop beyond my own project. I have spoken to current students about the supervision culture, and it matches how I like to work.

Common mistake to avoid: Saying you could not find a job; generic praise of the university
