PhD Interview Questions

Let’s make sure you walk in confident and walk out proud.
Here’s your ultimate PhD Interview Cheat Sheet — clear, simple, and based on what real supervisors look for.

Before the Interview

Preparation matters more than perfection.
Before the interview, take time to understand the people and place you’re applying to.

• Read some papers by your potential supervisor.
  Know their main research themes and recent projects. It shows genuine interest.
• Understand the department’s research priorities.
  Every university has key areas they focus on — align your proposal with those.
• Prepare 3–5 intelligent questions about their work or the program.
  Avoid generic ones like “What’s the funding like?”
  Instead, ask things like:
  “How does your team approach interdisciplinary research?”
• Review your own research proposal thoroughly.
  Expect questions about your methodology, objectives, and motivation.
• Practice your 2-minute research pitch.
  You’ll need it — short, sharp, and clear.

Your Research Pitch

Think of this as your “elevator talk.”
In two to three minutes, you should make them say, “That’s interesting!”

Here’s how to structure it:

• Use clear, simple language.
  No need to impress with jargon — impress with clarity.
• Start with the problem — not the method.
  What’s the issue you’re trying to solve?
• Explain why it matters.
  Why should anyone care? What’s the impact?
• Highlight what’s novel.
  What makes your approach different or better?
• Show that you understand the research gap.
  This tells them you’ve done your homework.
• Keep it under three minutes.
  If they want more, they’ll ask.

Questions About You

This part is all about fit. Supervisors want to see if you’ll thrive in their group.

• Why a PhD?
  Show passion for research, not just career ambition.
  Say something like: “I enjoy solving complex problems and want to contribute to real-world knowledge.”
• Why this university or department?
  Mention specific professors, resources, or projects that align with your interests.
• Why this topic?
  Connect your background and curiosity to the research area.
• What are your strengths?
  Link them to PhD success — persistence, curiosity, organization.
• What are your weaknesses?
  Be honest but strategic.
  Say something like: “I used to overcommit, but I’ve learned to manage my time better.”

They’re not looking for perfection — they’re looking for self-awareness.

Technical Questions

Yes, they will ask about your research plan.
But don’t panic — they’re testing how you think, not what you know.

• Be ready to defend your methodology.
  Why did you choose qualitative over quantitative?
  Why that sample size?
• Know your limitations.
  Every method has weaknesses. Acknowledge them.
• Discuss alternative methods.
  Show that you’ve explored different options.
• Be aware of ethics.
  If your work involves humans or data, know your ethical procedures.
• It’s OK to say, “I don’t know.”
  Follow it up with: “…but I’d explore it by doing X.”
• Think out loud.
• Supervisors like to see your reasoning process, not just the final answer.

Questions to Ask Them

Remember — a PhD interview is a two-way conversation, not an interrogation.
You’re also evaluating them.

Here are smart questions to ask:

• What does success look like for your PhD students?
• How often do you meet with students?
• What’s your supervision style?
• Are there collaboration or industry opportunities?
• What resources or labs are available?
• What’s the publication expectation?

Good questions show that you’re serious, practical, and thinking ahead.

Red Flags to Avoid

Many strong candidates lose points for small mistakes. Don’t be that person.

Avoid:

• ❌ Criticizing previous supervisors or universities.
• ❌ Being vague about your research interests.
• ❌ Not reading the interviewer’s recent work.
• ❌ Talking only about funding, not research.
• ❌ Interrupting or arguing defensively.
• ❌ Staying silent when asked, “Do you have any questions?”

These small things can make a big difference.

The Golden Questions You WILL Be Asked

Almost every PhD interview includes some version of these four golden questions.
Prepare short, confident answers for each.

  Use a simple formula: Problem → Gap → Solution → Impact.
• Why this university?
  Mention specific faculty, labs, or resources.
  Talk about culture fit and collaboration.
