What this interview looks like

A health-science university viva is usually a two-examiner affair: an internal examiner from the candidate's own college and an external examiner from another college in the same university, sitting for 5 to 15 minutes per candidate at the end of the practical examination, with the practical record book or log book open on the table. Marks are a fixed slice of the practical paper, often 10 to 20 out of 50 or 100, and in many universities a candidate must pass the practical and viva separately from theory. The external asks the first question, usually from the record, then moves to classifications, mechanisms, principles of a procedure and one applied question; the internal fills gaps and checks attendance and record completion. A PhD viva voce is longer, typically 45 to 90 minutes: the candidate presents the thesis for 20 to 30 minutes, then the external examiner, who has already sent a written report, cross-examines on methodology, novelty, statistics, limitations and the published papers, with the supervisor and research-committee members present and an open-house audience in most Indian universities. The ExamPilot mock compresses either into about 15 minutes with the same shape: a short introduction, a subject round with a subject expert, a round on your record book or thesis chapters, and a brief close, scored against what a real external rewards: clear definitions, correct sequence, honest admission of limits and no invented figures.

How it is weighted

A PhD viva is pass, pass with minor or major corrections, or re-submission; the external examiner's written report and the viva decide together. M.Tech and MPhil dissertation vivas usually carry a fixed share of the project credits, often 40 to 60 percent split between presentation, viva and the written report. UGC 2016 and 2022 regulations require the viva to be open; procedures vary by university.

Who this is for

Research scholars whose thesis has been evaluated by external examiners and who are scheduled for the final open viva voce; postgraduate students facing the M.Tech, MPhil or MSc dissertation viva before an internal and external examiner; and PhD scholars preparing the synopsis presentation, pre-submission seminar or six-monthly research advisory committee review. Covers science, engineering, health science and social-science theses; questions are discipline-neutral and work from your own abstract.

The panel focuses on

  • Stating the research question, gap and contribution in two minutes without reading slides
  • Defending the methodology: design, sampling, instruments, validity, controls and why alternatives were rejected
  • Statistics you actually used: assumptions, test choice, effect size, multiple comparisons, what the p-value does and does not say
  • Limitations and threats to validity stated before the examiner finds them, and what they do and do not undermine
  • Ethics and integrity: IEC or IAEC approval, consent, data management, plagiarism checks, authorship on published papers
  • Future work, generalisability and answering a hostile question calmly with evidence from your own chapters

What to expect

4 rounds · 10 minutes

A ten-minute oral examination of the kind held at the end of a laboratory course or project: school board practicals, engineering lab and project vivas, pharmacy and nursing practicals, dissertation and thesis defences. One external examiner, sometimes seated with the internal teacher, asks the candidate what they did, why it works, what they observed and what could go wrong, then looks at the record file or project and asks one question that tests whether the work is the candidate's own. The examiner escalates when answers are correct, gives one hint when the candidate is stuck, and never teaches during the viva.

  1. Round 1

    Introduction

    · 1:00

    Settle the candidate and establish exactly which experiment, practical, project or thesis the viva will be about, so that the subject questions can be anchored to work the candidate actually did.

    Prof. Devendra Kulkarni
    1–2 questionsup to 1 follow-up each
  2. Round 2

    Viva on concepts and experiments

    · 7:00

    Test whether the candidate understands the principle behind the experiment or project they did, can describe the procedure and observations accurately, knows the precautions and sources of error, and can reason about a change in conditions. Separate genuine understanding from a memorised record file.

    Prof. Devendra Kulkarni
    4–6 questionsup to 2 follow-ups each
  3. Round 3

    Record file or project

    · 1:00

    Check that the record file, activity or project is the candidate's own work and that they understand it: why they chose it, what the data or result was, what went wrong and what they would improve.

    Prof. Devendra Kulkarni
    1–1 questionsup to 1 follow-up each
  4. Round 4

    Closing

    · 1:00

    End the viva courteously and formally, as an external examiner does, without feedback, marks or any hint about the result.

    Prof. Devendra Kulkarni

Sample questions

Health & Research Viva Thesis defence interview questions

Questions panels commonly ask in the Health & Research Viva Thesis defence interview, with what a strong answer covers. Practise them aloud with the AI panel.

  1. Research question

    State your research question, the gap it fills and your main contribution in two minutes, without looking at your slides.

    What a strong answer covers

    A clear, concise question, a specific gap in prior work and one or two contributions stated precisely, showing command of the thesis. Avoid reading slides or burying the contribution in background.

  2. Methodology

    Why did you choose a cross-sectional design rather than a cohort, and what does that prevent you from concluding?

    What a strong answer covers

    Gives practical and scientific reasons for the design, and states that a cross-sectional study shows association at one point in time but cannot establish temporal sequence or causation. Avoid claiming causality.

  3. Statistics

    You used a t-test across several subgroups. How did you check its assumptions, and did you correct for multiple comparisons?

    What a strong answer covers

    Mentions checks of normality and variance, alternatives such as non-parametric tests, and corrections for multiple comparisons such as Bonferroni or explaining why not needed. Avoid treating p-values as proof of importance.

  4. Interpretation

    Your p-value is 0.04 but the effect size is small. How do you interpret this for practice?

    What a strong answer covers

    Explains that statistical significance does not imply practical importance, discusses confidence intervals and clinical or practical relevance, and states conclusions cautiously. Avoid overstating the findings.

  5. Limitations

    What is the most serious limitation of your study, and does it undermine your main conclusion?

    What a strong answer covers

    Names a real limitation such as selection bias, small size or measurement error, explains its likely direction and effect, and whether the core conclusion still holds. Avoid listing trivial limitations to avoid the real one.

  6. Research ethics

    Show us the ethics approval for your study and explain how you handled consent and data storage.

    What a strong answer covers

    Describes institutional ethics committee approval, informed consent procedures, anonymisation and secure storage of data, and any special protections. Avoid treating ethics as a paperwork step.

  7. Authorship

    One of your published papers has five co-authors. What was your specific contribution, and how was authorship decided?

    What a strong answer covers

    Clearly states personal contribution to design, data, analysis or writing, and explains authorship criteria agreed with the team. Avoid vague answers or claiming others' work.

  8. Generalisability

    How generalisable are your findings beyond the setting you studied?

    What a strong answer covers

    Describes the population and setting studied, the features that might differ elsewhere such as health system, culture or equipment, and the kind of replication or multi-site study that would test generalisability. Avoid claiming the findings apply everywhere.

  9. Defending the thesis

    An examiner says your conclusion is not supported by your data. How do you respond?

    What a strong answer covers

    Listens fully, asks for the specific concern if unclear, refers to particular tables or results in the thesis, explains the reasoning, and concedes and offers revisions where the examiner is right. Avoid becoming defensive or dismissing the examiner's report.

How scoring works

A report you can act on

  1. Every round is scored on the rubric

    Each interviewer scores only the criteria their round covers. Weights add up to your overall score out of 100.

  2. Only what you actually said counts

    Feedback quotes your own answers. Rounds you skip show as “Not assessed” rather than a zero.

  3. Communication is always measured

    Fluency, clarity, confidence and structure are tracked across the whole interview, in any language.

  4. Pass mark, then a plan

    You see the pass mark for this interview, your gaps, and the courses that close them fastest.

Scored on

  • Conceptual understanding40%

    States the principle, law or formula behind the experiment or project correctly and in their own words; explains why the method works rather than only what the steps are; handles a why or what-if question with reasoning; does not confuse related concepts or recite a definition that does not answer the question.

  • Experimental procedure & observation30%

    Describes the actual procedure, apparatus or tools, readings or data and how they were processed; knows the units, the expected result and the order of magnitude they obtained; names sources of error and the precautions that address them; for a project, knows the data, method and limitations of their own work.

  • Clarity of explanation20%

    Answers the question actually asked in short, ordered sentences; uses correct technical terms and units; can explain the same idea more simply when asked; does not ramble or bury the answer in unrelated recall.

  • Confidence & honesty10%

    Speaks steadily, holds a correct answer when gently challenged, corrects themselves when shown an error, and says I am not sure rather than guessing; recovers after a hint instead of freezing.
