What this interview looks like

In an Indian engineering college, every lab course ends in a practical examination where the student performs one experiment or writes one program and then faces a viva voce from an internal examiner and, in the end-semester university exam, an external examiner appointed by the university. The viva typically lasts five to fifteen minutes per student, and the examiner opens the lab record or the just-completed experiment and asks the student to explain the setup, the readings, the theory behind them and what would change if a condition changed. The final-year project viva is longer: a panel of the guide, an internal examiner and an external examiner, often from industry, hears a presentation and demo and then questions each team member on the problem, design choices, their own module and the results. Marks for the viva are set by the university scheme and usually form a part of the practical or project marks, with the exact split varying by university. The ExamPilot mock compresses this into a twelve-minute viva with one examiner who opens your record, probes one subject in depth, tests what-if reasoning on a scenario from the lab or project, and closes without revealing marks.

What to expect

4 rounds, one after another

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. Raghunath 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. Raghunath 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. Raghunath 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. Raghunath Kulkarni

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.
