Two lines of every application invite questions you can predict: the degree you studied and the work you have done. A panel can test the first in a minute and the second in one follow-up, and at IIM Bangalore a candidate found to have given incorrect information about work experience is barred from applying to its programmes for the next three years.
Prepare both from what you can explain and show: five core ideas of your subject, a work story with your own part and a number, and three honest sentences for a gap, a switch or a low mark.
Questions on your degree test whether you can explain it simply
Questions on your degree check whether you understood what you studied well enough to explain it to someone outside it. Prepare five core ideas of your own subject. For each, write two sentences a non-specialist can follow, one place where you have seen it used, and a number where there is one. Here is one idea from each of four kinds of degree:
| Degree | One core idea, plainly | Where you see it, with a number |
|---|---|---|
| Engineering (computer science) | binary search halves a sorted list at every check | 20 checks find one entry among 10,00,000 sorted ones |
| Commerce | compounding: interest earns interest | ₹1,00,000 at 8 % a year grows to ₹1,46,933 in five years |
| Science (statistics) | a A number from a statistical test that says how surprising data at least as extreme as yours would be if a chosen model, such as a fair coin, were true. describes the data under a model, not the model’s chance of being true | a trial’s p = 0.03 is not a 97 % chance that the drug works |
| Humanities (economics) | inflation erodes what money buys; India targets 4 % consumer-price inflation, within 2 to 6 % | after a year of 6 %, ₹100 buys what ₹94.34 did |
The p-value row follows the American Statistical Association’s statement on p-values, and the inflation target is the Reserve Bank of India’s. The program works out the other three numbers; change one to a number from your own subject:
"""The numbers in the lesson's table of core ideas, worked out: how many checks binary search needs to find one entry
among a million sorted ones, what compounding makes of 1 lakh rupees at 8 % a year for five years, and how much of
100 rupees' buying power is left after a year of 6 % inflation. Press Edit and put in a number from your own subject."""
import math
def rupees(x):
"""Indian digit grouping: 146933 -> 1,46,933."""
s = str(round(x))
head, tail = s[:-3], s[-3:]
groups = []
while len(head) > 2:
groups.insert(0, head[-2:])
head = head[:-2]
return ",".join(([head] if head else []) + groups + [tail])
entries = 1_000_000
checks = math.floor(math.log2(entries)) + 1
print(f"Binary search: at most {checks} checks to find one entry among {rupees(entries)} sorted entries")
principal, rate, years = 100_000, 0.08, 5
value = principal * (1 + rate) ** years
print(f"Compounding: {rupees(principal)} rupees at 8 % a year for {years} years grow to {rupees(value)} rupees")
inflation = 0.06
left = 100 / (1 + inflation)
print(f"Inflation: after a year of 6 %, 100 rupees buy what {left:.2f} rupees bought a year earlier") Output
Binary search: at most 20 checks to find one entry among 10,00,000 sorted entries Compounding: 1,00,000 rupees at 8 % a year for 5 years grow to 1,46,933 rupees Inflation: after a year of 6 %, 100 rupees buy what 94.34 rupees bought a year earlier

A work story names the team, your part, a number and a lesson
Questions on your work ask what you did, so a work story: A short account of one piece of your work for an interview: what the team did, what you did yourself, a result with a number and what you would do differently. holds four things: what the team did, what you did yourself, a result with a number, and what you would do differently. The program checks five stories and prints the follow-up each gap invites:
"""Five work stories checked for what a panel listens for: what the team did, what you did yourself (not "we"), a
result with a number, and what you would do differently. A missing part prints the follow-up it invites. The stories
are invented. Press Edit, write your own story into STORIES, and run it again."""
INVITES = {
"team": "What was the team trying to do?",
"mine": "What did you do yourself?",
"result": "How much, and how do you know?",
"lesson": "What would you do differently?",
}
STORIES = [
("Rohit, technical sales", {
"team": "Our team sells switchgear to factories in two districts.",
"mine": "I took over 14 dormant accounts and visited each one with a maintenance plan.",
"result": "Nine of them ordered again within six months, about 38 lakh rupees of orders.",
"lesson": "I would ask for the maintenance logs before the first visit, not after it.",
}),

"team": "My branch opens about 300 accounts a month.",
"mine": "We reduced the time it takes to open an account.",

Only Rohit’s story holds. Ananya’s “we reduced the time” hides her part and has no number, and Dev’s stock-outs “fell a lot”. The program cannot tell that Dev’s “data beats instinct” is a lesson anyone could claim: that judgement is yours.
Your story must match your documents
IIM Calcutta asks for an employer’s letter giving your start date, end date, designation and role, with payslips from each employer. IIM Bangalore will not consider further a candidate found to have given incorrect information about work experience. Tell your story in the months and the title those papers show.
Told that way, a story survives both the panel’s follow-up and the documents on the table.
Key idea
A work story holds the team’s aim, your own part said with “I”, a result with a number and a real lesson, in the months and the title your documents show.

A gap, a switch or a low mark takes three sentences
A gap, a switch of field or a low mark is a line a panel will ask about, and an answer that hides it costs more than the line itself. Tell it in three sentences, well under a minute: the fact, what you did, what it taught you. Walk through Rohit’s record, where all three appear:
- Third semester
A failed paper, cleared at the next attempt low mark
The fact: he failed one paper in his third semester of electrical engineering. What he did: cleared it at the next attempt and finished with 68 % overall. What it taught him: to start revising a month earlier, which he has done since.
- Nine-month gap
Preparing for a recruitment exam, tutoring on the side gap
The fact: nine months after graduating, spent preparing for a public-sector engineering exam he did not clear. What he did: tutored six students in mathematics part-time. What it taught him: that he liked explaining technical things to the people who use them.
- First job
Technical sales of switchgear, 20 months switch
The fact: he joined an electrical equipment maker's sales team, not a design team. What he did: took over 14 dormant accounts, and nine ordered again within six months. What it taught him: that the gap year had pointed him to the right work.
- Now
The switch becomes the start of his chain
The three lines now read as one story. He wants to run a sales region, and the gap he names is the planning and finance he lacks, which is what an MBA adds.
The timeline has 4 events, from Third semester to Now.
Each answer states the fact first and never argues with it. The third sentence does the work: it turns the line into a step towards the role his chain ends in.
Defending a gap at length
A two-minute defence of a nine-month gap tells the panel the gap worries you. Three sentences tell it you have dealt with it.

Interview questions
Three questions apply the method to harder cases:
-
Mid
An engineer with two years in sales is asked to explain a core idea of their degree, and goes blank. What should they have prepared, and how do they recover in the room?
-
Fresher to mid
Your story says, "We cut delivery delays by 18 %." The panel asks what you did yourself. What makes a strong reply, and what if your part was small?
-
Fresher to mid
You spent 11 months after graduating preparing for a government recruitment exam that you did not clear. How do you explain the gap in under a minute?
Not affiliated
Based on public information about the Indian Institutes of Management. MySmartCoPilot is not affiliated with the Indian Institutes of Management, and the Indian Institutes of Management’s real admission rules may differ from what this lesson describes.
Flashcards · 6 cards
Recall it, then check
Say the answer to yourself before you look: recalling it is what makes it stick.
-
How do you prepare for questions on your degree?
Five core ideas of your subject, each in two sentences a non-specialist can follow, with one place you have seen it used and a number, prepared a step past the definition.
-
How many checks does binary search need to find one entry among 10,00,000 sorted ones?
20: each check halves the list still in doubt, and 2²⁰ is just over 10,00,000.
-
What does a p-value of 0.03 in a trial not mean?
It is not a 97 % chance that the drug works. It describes how surprising the data would be under a chosen model, not the chance that the model is true.
-
What does a work story hold?
What the team did, what you did yourself (said with "I"), a result with a number, and what you would do differently, told in the months and the title your documents show.
-
Why must your work story match your documents?
Institutes check: IIM Calcutta wants an employer's letter (dates, designation, role) and payslips, and IIM Bangalore can bar an applicant whose work-experience details were incorrect for three years.
-
How do you answer a question on a gap, a switch or a low mark?
In three sentences, well under a minute: the fact, what you did, what it taught you. State the fact first and never argue with it; a long defence tells the panel it worries you.
