What this mock is, and what it is not
This page gives you a complete 20-minute IIM panel interview you can run tonight: a timed script with the questions, the follow-ups a panel adds when it hears a weak answer, three profile branches (fresher, engineer with work experience, commerce and CA), a five-criterion self-score sheet with descriptors, and a scored sample so you can see how the sheet is used. Everything on it is written by TalkDrill. It is not a transcript of a real IIM interview and no real candidate is quoted; our transcripts page is also TalkDrill-written and says so. The reason to run it is arithmetic: per IIM Calcutta's MBA 2027-29 admission procedure, the personal interview is 48 of 100 points in final selection and the CAT score is 30. A mock is the only preparation that practises the 48.
No IIM publishes how long its interview lasts in the policy pages we have read, and candidate accounts vary by campus and panel. The script runs to twenty minutes with a hard stop as our rehearsal setting. A hard stop is the point: a panel that has made up its mind may close early, and the script teaches you to put your best material in the first eight minutes.
- Your one-page profile sheet (stream, marks, project, jobs with dates, hometown, two hobbies). The roadmap builds it on day 2.
- A timer you can see, a phone recording from across the table, and a chair at a table, not a bed.
- A panel: one to three people reading the script, or the TalkDrill AI mock interview, given your profile and asked to follow this script.
- The score sheet below, printed or copied into a notebook, one column per mock.
How to set it up: three ways
| Setup | How | Best for | Weakness |
|---|---|---|---|
| Human panel | One to three people sit across a table with the script. The one in the middle leads; the others take the follow-ups marked F. They do not smile, nod or help. Hard stop at 20 minutes. | Composure, panel manners, the feeling of three faces | Friends go soft; tell them every follow-up is compulsory |
| AI panel on TalkDrill | Open the AI mock interview, give your profile and say it is an IIM panel. The AI asks, listens and follows up on what you said. Keep your own 20-minute timer and your own phone recording for scoring. | Repetition, honest pushback, late-night practice, no scheduling | It does not read your body language; sit as you would in the room anyway |
| Alone with a recorder | Read each question aloud in a flat voice, answer, read the follow-up, answer. Never pause the recording. Score it the next morning, not the same night. | A first baseline when you have nobody yet | You will skip the follow-ups that scare you; read them all |
Whichever setup you use, keep two rules. First, no restarts: an answer that went badly is the most useful minute in the recording. Second, score the recording, not your memory of it, and score it against the descriptors, not against how you felt.
The 20-minute panel script (written by TalkDrill)
Timings are cumulative. P1, P2 and P3 are the three panel members; with one interviewer, one person reads all three. Lines marked F are follow-ups: the panel asks them when the answer was vague, and a good panel asks them anyway.
0:00 to 2:30, the opening
- P1: Good morning. Please sit. Tell us about yourself in about two minutes.
- F (P2, at 2:00 if still talking): Thank you, that is enough. (Interrupting the introduction is deliberate; candidates report that real panels often do it.)
- F (P1): You said you are from [town]. What is [town] known for, economically?
2:30 to 8:00, academics
- P2: Which subject did you score highest in during graduation? Explain one concept from it to me as if I studied history.
- F: And the lowest? Why?
- P2: Your final-year project. One sentence on what it did, one on what was yours alone, one on what did not work.
- F: If you had six more months and a budget, what would you change?
- P3: Here is a question from your syllabus. (Pick one from the stream page; engineers get a fundamentals question, commerce candidates an accounting or economics one, CAs a tax or audit one.) Take your time.
- F (if the candidate says they do not know): How would you find out? Tell me the first thing you would look up.
8:00 to 12:00, work or profile
- P1 (work experience): Walk me through one thing at work that would not have happened without you.
- F: What did it cost? Who disagreed with you? What number did it move?
- P1 (fresher): Tell me about one responsibility in college where something went wrong. What did you do?
- F: What would your teammates say you did badly?
- P3: Why leave a job after [N] months? (Or, for freshers: why not work for two years first?)
12:00 to 16:00, why MBA and goals
- P2: Why an MBA? And please do not say leadership.
- F: What did you try without an MBA? Why did that not work?
- P2: Why now rather than in two years?
- P1: You hold other calls. If we and [other institute] both offer, what do you do, and why?
- F: Name one course or faculty area here that you have actually looked at.
- P3: Where are you in five years? And ten?
16:00 to 19:00, the world and the pressure
- P3: What is one piece of economic news from this week that you have an opinion on? Give me the fact, then the opinion.
- F: What would someone who disagrees with you say? Is that person wrong?
- P1: A hypothetical. (Pick one: you are the collector of your home district with a fixed budget and two urgent problems; or your company must cut 10 per cent of costs without layoffs.) Think aloud.
- P2 (stress line, delivered flat): I do not think you have answered a single question directly today. Why should we take you?
19:00 to 20:00, the close
- P1: Anything you want to ask us? (One short, specific question or a polite no. Not "how did I do".)
- P1: Thank you. You may go. (Stand, thank the panel by looking at each, push the chair in, leave without lingering.)
Profile branches: fresher, engineer with work, commerce and CA
The script above is the spine. The panel's emphasis changes with the form in front of them, and your mock should too.
| Profile | Where the panel spends the extra minutes | Swap into the script | What they are checking |
|---|---|---|---|
| Fresher (final year or just graduated) | Academics, 8 to 10 minutes. The project. College responsibilities. Why not work first. | Two extra syllabus questions at 6:00; "what did you read outside the syllabus"; "which placement offers did you refuse and why" | Whether you understand your own degree, and whether an MBA now is a plan or an escape from placements |
| Engineer with 0 to 3 years at a services or product company | Work, 6 minutes. What in the project was yours. Why leave. Technical fundamentals from the degree, which most have forgotten. | "Explain what your company sells and who pays"; "what did your appraisal say"; one first-year engineering fundamentals question | Whether you can tell impact from attendance, and whether you left engineering because you failed at it |
| Commerce graduate or CA | Applied accounting, economics and tax, 7 minutes. Current affairs turned into numbers. Why MBA when you already have a profession. | "Read me a balance sheet line that worries you about [a listed company]"; "explain GST input credit to a shopkeeper"; "why not practise as a CA" | Whether the professional knowledge is live, and whether the MBA is a route to general management or a way out of articleship |
| Family business | The business itself, 6 minutes. Numbers, margins, what you would change, why an MBA rather than two years inside it. | "What is your turnover and your margin"; "what does your father think you will learn that he cannot teach" | Whether you know the business as an operator or as a son or daughter |
| Career gap or a changed stream | The gap, 3 minutes, early. Then the normal script. | "What did you do in those fourteen months, month by month" | Honesty and whether the story is the same each time it is asked |
The questions by profile page has the full sets, and the why-MBA page has the frame the 12:00 block is testing. Ask your panel to pick the branch before the mock and not tell you which extra questions they chose.
The self-score sheet: five criteria, 1 to 5
Score the recording, criterion by criterion, with the descriptors below. The total out of 25 is less useful than the two lowest numbers, which are the only things the next week should work on. Keep one column per mock so that mock 1 and mock 6 sit side by side.
| Criterion | 1 | 3 | 5 |
|---|---|---|---|
| Structure: did each answer have a point, support and a stop? | Answers start mid-thought and end when interrupted; the point, if any, comes last | Most answers open with the point; some trail on after it is made | Point first, one or two supports, a clean stop; the panel never has to cut you off |
| Depth: could you go two levels down on your own claims? | The first follow-up produces "I was part of the team" or a repeat of the first answer | One level down is solid; the second follow-up produces guesses | Two levels down with specifics (a number, a name, a trade-off); limits stated before being asked |
| Honesty: did you admit what you did not know without collapsing? | Bluffing on the syllabus question, or a long apology that derails the next three answers | "I do not know" said, but followed by silence rather than a method | "I do not know; here is how I would find out", calmly, and the next answer is unaffected |
| Composure: pace, pauses, recovery after interruption and the stress line | Speed rises through the interview; the stress line produces defensiveness or a shaky voice | Steady until interrupted; one visible recovery that took a few seconds | Pauses used on purpose; the interruption is absorbed; the stress line is answered in two calm sentences |
| Language: clear sentences, fillers, tense, register | Fillers in most sentences ("basically", "actually", "like"); present progressive for states ("I am having two years' experience"); sir after every clause | Fillers in long answers only; a few tense slips; sentences sometimes too long to finish | Short sentences, correct tense, one "sir" or "ma'am" per answer at most, no filler run longer than two |
Two scorers rarely agree to the point, but with these descriptors they argue about one step, not three. If you are scoring alone, score the next morning; the same night you are either too kind or too cruel. The language criterion is the one where first language shows most; the spoken English page has the drills by language, Hindi first, then Marathi, Tamil, Telugu, Gujarati, Bengali, Kannada and Malayalam.
A scored sample (written by TalkDrill)
Three exchanges from one TalkDrill-written mock, with the scorer's notes. The candidate, Arjun, is fictional: a computer science graduate with 14 months at an IT services company in Hyderabad, Telugu first language, holding an IIM Kozhikode call.
Exchange 1, at 8:00 (work)
P1: Walk me through one thing at work that would not have happened without you.
Arjun: Sir, basically I was in the testing team for a banking client, and basically we were having a lot of defects coming late. So I proposed we write automated checks for the payment module, and I wrote the first forty of them myself in three weekends. After that the late defects in that module dropped; my lead's number was about a third fewer in the next release.
P1 (F): Who disagreed?
Arjun: My lead, at first. He said the client had not paid for automation. I did it on my own time and showed him the first ten passing before he agreed to count it.
Scorer: Structure 4 (point, support, stop; the opening clause wasted five seconds). Depth 4 (a number, a person, a trade-off; "about a third" is honest hedging). Language 2 (two "basically", "we were having"). The exchange is strong; the English is the drag.
Exchange 2, at 6:30 (syllabus)
P3: What is the difference between a process and a thread?
Arjun: Sir, a process has its own memory space, and threads inside a process share that memory, so threads are cheaper to create and to switch between, but one thread corrupting shared memory affects the others.
P3 (F): So why does a browser use processes per tab instead of threads?
Arjun: I think for isolation, sir, so that one tab crashing does not take the others, and for security between sites. I am not certain whether memory cost was the reason they moved to it or a cost they accepted.
Scorer: Depth 5 (two levels, the limit stated unprompted). Honesty 5. Composure 4. This is the exchange he should listen to when the stress line rattles him.
Exchange 3, at 18:30 (stress line)
P2: I do not think you have answered a single question directly today. Why should we take you?
Arjun: Sir, I, actually, I think I did answer, like, the process question was direct, and the work one. Maybe my why-MBA answer was long, I accept that. I think you should take me because I have shown I do things without being asked, and I want to learn to decide what gets done, which is what I cannot learn in testing.
Scorer: Composure 2 for the first sentence, recovering to a 4 by the end; score the criterion 3. Language 2 (the filler run "I, actually, I think, like"). The second sentence is the answer; the fix is to say it first. Week 5, day 3 of the roadmap is the filler drill for exactly this.
Mock total for Arjun: structure 4, depth 4, honesty 5, composure 3, language 2. The two lowest are language and composure, and they are linked: the fillers multiply under pressure. His next week is pauses instead of fillers and one more mock with the stress line asked twice. The question bank has sixty more questions with frames to feed the next mock.
The common faults, and the fix for each
| Fault | How it sounds | Fix, and where in the plan |
|---|---|---|
| The three-minute introduction | School, every mark, every certificate, the hobby list; the panel may interrupt at two minutes and the candidate never reaches why they are there | Three beats, two minutes, rehearsed to a timer: where from, what you studied and did, why here. The introduction guide; roadmap week 1, day 3 |
| "I was part of the team that" | Impact described as attendance; the first follow-up has nowhere to go | Rewrite each work story as a decision that was yours, with its cost and its number. Roadmap week 2, days 4 and 5 |
| Bluffing the syllabus question | A confident wrong answer, then a second one, then a third; the panel now doubts every earlier answer | Say "I do not know" in the first ten seconds and give a method. Practise the line until it is calm. Roadmap week 3, day 6 |
| Why MBA with "leadership" and "management is my passion" | No gap, no attempt, no evidence; the panel hears a brochure | The frame: gap, what you tried, goal, why this programme, evidence. Why MBA page; roadmap week 3, day 1 |
| Opinion without a fact | "I think the economy is doing well" with no number, no source, no other side | Fact, two sides, your view, three sentences, from a notebook you have kept for three weeks. Roadmap week 3, day 3 |
| Speed rising under stress | The last five minutes are noticeably faster than the first five, and the fillers multiply | A half-second pause where each filler was; the stress line asked twice per mock in week 5. Filler words guide |
| Answering the panel member who smiled | Eye contact with the friendliest face for the whole interview | Answer the one who asked, glance to the others at the point, return. Panel interview tips; roadmap week 5, day 5 |
How often, and when in the six weeks
The six-week roadmap places seven mocks, and the placement matters as much as the count.
- Week 1, day 4: the baseline. Full script, no preparation beyond the profile sheet. Score it on day 5 and circle the two lowest criteria. Everything until week 5 works on those two.
- Week 2, day 6 and week 3, day 5: focused mocks. Academics and work only, then why MBA, goals, current affairs and hometown only. Twenty minutes each, with follow-ups. They test the week's material under pushback, which reading never does.
- Week 5, days 1, 4 and 6: three full mocks. Day 1 in formal clothes at a table; day 4 with a human who interrupts, or the AI asked to include the stress line; day 6 after a 20-minute WAT, the WAT-then-PI order candidates report at IIM centres. Compare day 6 with the baseline in writing.
- Week 6, day 3: ten minutes. Introduction, why MBA, one academic question. A warm-up, not a test. Then listen to the baseline and this recording back to back; the improvement you can hear is what steadies you on the morning.
If you have three weeks, run the baseline on day 2, one focused mock at the end of week 1, two full mocks in the last week and the ten-minute warm-up the day before. If you have three days, run the full script once tonight, score it tomorrow morning, fix one thing, and run it once more the night before. The AI mock interview is built for exactly the night when nobody is free to play the panel, and the HR interview questions book covers the general questions that appear in the 12:00 block of every B-school interview.
