🔥 Challenge Yourself First!

Before reading further, pause and think—how would YOU answer these actual interview questions?

1 The Dynamic Pricing Question

“How is dynamic pricing decided in your company? How is it different from airline companies?”

This tests whether you understand the business side of your tech work—not just what you code, but why it matters.

✅ Success Strategy

Structure your answer: (1) Factors affecting pricing: demand forecasting, competitor rates, seasonality, booking window, customer segments; (2) Tech enablers: ML models analyzing historical data, real-time demand signals, A/B testing; (3) Difference from airlines: hotels have longer booking windows, less perishable inventory (can sell same room night after night), more flexible cancellation—so pricing algorithms account for these. Airlines have stricter seat perishability and more complex yield management. Show you understand the business logic behind the code!

2 The Bitcoin Deep-Dive

“Tell me about Bitcoin. Who started it?”

Tech candidates are expected to know emerging technologies—both the mechanism and the backstory.

✅ Success Strategy

Cover both tech and economics: (1) Technology: decentralized digital currency using blockchain, transactions verified by miners, cryptographic security; (2) Economics: limited supply (21 million cap), deflationary by design, high volatility, used as store of value and speculative asset; (3) Origin: Created by Satoshi Nakamoto (pseudonym, identity unknown) in 2008-2009 whitepaper. First block mined January 2009. Mention current status: institutional adoption, regulatory debates, environmental concerns from mining. Show breadth of understanding!

3 The Central Tendencies Question

“What are the central tendencies? Which one is most important?”

Statistics fundamentals with a twist—they want you to go beyond listing to explain when each is useful.

✅ Success Strategy

Go beyond definitions: (1) Mean—average of all values, best for symmetric distributions without outliers; (2) Median—middle value, robust to outliers, ideal for skewed data like income; (3) Mode—most frequent value, useful for categorical data. Which is most important? “It depends on context”—for salary analysis, median is better (outliers don’t skew it); for quality control, mean might be appropriate. Show nuanced thinking by explaining that the “best” measure depends on data distribution and analysis objective.

4 The Distribution Question

“What is a discrete distribution? Can you name one? What are its parameters?”

Testing depth of statistical knowledge—definitions, examples, and technical parameters.

✅ Success Strategy

Structure: (1) Definition: Distribution where variable takes countable, distinct values (integers); (2) Examples: Binomial (n trials, p probability), Poisson (λ average rate), Geometric (trials until first success); (3) Binomial parameters: n (number of trials), p (probability of success); (4) Use case: Modeling number of website clicks (Poisson), pass/fail scenarios (Binomial). If you mention Poisson, know λ (lambda) is both mean and variance. Show you can apply these in real scenarios!

1
Phase 1

Icebreaker & Profile-Based Questions

“Tell us briefly about yourself.”
Classic opener—structure is everything.
💡 Strategy

Keep it structured: Start with education (NIT, CS), move to work experience (company, role, key projects), end with motivation for MBA. Under 2 minutes. Don’t just list facts—create a narrative that leads naturally to why you’re here.

“Where are you currently working?”
Verification plus industry positioning.
💡 Strategy

Answer factually but highlight the company’s industry position or notable achievements. “I work at [Company], India’s leading online travel aggregator, which processes X million bookings annually.” Position your company’s relevance to the business world.

“How is your company different from other similar websites?”
Testing business understanding of your employer.
💡 Strategy

Focus on USPs: technology (better search algorithms, personalization), pricing models (dynamic pricing, best price guarantees), customer experience (24/7 support, easy cancellations), or partnerships (exclusive hotel deals, airline tie-ups). Show you understand the competitive landscape, not just your code.

“Is it full stack?”
Clarifying your technical role.
💡 Strategy

Be ready to explain technical concepts for a non-technical audience. If full-stack: “Yes, I work on both frontend (what users see) and backend (server, database).” Clarify your specific role in the stack. Be prepared for follow-ups on technologies used.

2
Phase 2

General Awareness & Tech Questions

“Tell me about Bitcoin.”
Testing awareness of disruptive technologies.
💡 Strategy

Cover both tech mechanism and economic perspective: (1) Decentralized digital currency using blockchain; (2) Mining process and proof of work; (3) Limited supply (21 million cap); (4) High volatility and speculative nature; (5) Current debates: institutional adoption, regulation, environmental impact. Show breadth of understanding.

“Who started it?”
Testing knowledge of tech history and key figures.
💡 Strategy

Satoshi Nakamoto—a pseudonym, real identity unknown. Published the whitepaper in 2008, first Bitcoin block (Genesis Block) mined in January 2009. Add context: the mystery itself is notable; speculation ranges from individuals (Hal Finney, Nick Szabo) to groups. Shows you know the story beyond surface facts.

3
Phase 3

Business & Analytical Questions

“How is dynamic pricing decided in your company?”
Connecting your tech role to business outcomes.
💡 Strategy

Tie your answer to data science and business insights: (1) Demand forecasting based on historical data; (2) Real-time competitor rate monitoring; (3) Seasonality and event-based adjustments; (4) Customer segmentation (loyalty members, first-timers); (5) ML models optimizing price-demand elasticity. Show you understand the “why” behind the algorithms.

“How is it different from airline companies?”
Testing comparative business analysis skills.
💡 Strategy

Key differences: (1) Booking windows—hotels often longer lead times, airlines have last-minute premium; (2) Inventory perishability—airline seat is gone forever after flight, hotel room available next night; (3) Price sensitivity—different customer behaviors; (4) Peak variations—airlines have hourly peaks, hotels more daily/weekly. Show nuanced industry understanding.

“Draw the demand and supply graph.”
Basic economics visualization test.
💡 Strategy

Be quick and neat: X-axis = Quantity, Y-axis = Price. Demand curve slopes downward (as price decreases, quantity demanded increases). Supply curve slopes upward (as price increases, quantity supplied increases). Mark equilibrium point where curves intersect. Mention what causes shifts: demand (income, preferences), supply (production costs, technology).

4
Phase 4

Statistics & Quantitative Reasoning

“What are the central tendencies?”
Statistics fundamentals.
💡 Strategy

Go beyond listing: Mean (average—sum divided by count), Median (middle value when sorted), Mode (most frequent value). Mention when each is useful: mean for symmetric distributions, median for skewed data (like income), mode for categorical data. Show application awareness.

“Which one is most important?”
Testing analytical nuance—there’s no single right answer.
💡 Strategy

The best answer: “It depends on context.” For salary analysis, median is better (CEO salaries don’t skew it). For exam scores with normal distribution, mean works well. For fashion sizes, mode matters most. Show you understand that choice depends on data distribution and analysis objective—not that one is universally “best.”

“What is a discrete distribution? Can you name one?”
Testing statistical distribution knowledge.
💡 Strategy

Discrete distribution: variable takes countable, distinct values (integers). Examples: Binomial (number of successes in n trials), Poisson (events in fixed interval), Geometric (trials until first success), Bernoulli (single trial, two outcomes). Also mention others to show breadth—Negative Binomial, Hypergeometric.

“What are its parameters?”
Deep-dive on distribution specifics.
💡 Strategy

Be prepared for follow-ups: Binomial has n (trials) and p (probability); Poisson has λ (lambda—mean rate); Geometric has p (probability). Know formulas and simple scenarios: “Binomial models coin flips—10 flips (n=10), 50% heads (p=0.5). Poisson models website hits per hour with average rate λ.” Apply to real examples!

🎯 Key Takeaways for Future Candidates

The most important lessons from this interview experience.

1

Expect a Blend of Domain-Specific, Business, and Stats-Based Questions

The interview seamlessly moved from tech work (full-stack role) to business strategy (dynamic pricing) to pure statistics (distributions). IIM-C values candidates who can bridge technical expertise with business thinking and quantitative rigor.

Action Item: Prepare answers that connect all three: “In my role, I use statistical models (e.g., Poisson for demand forecasting) to build features that drive business outcomes (e.g., dynamic pricing optimization).”
2

For Engineers, Brush Up on Core Statistics and Economic Graphs

Questions on central tendencies, discrete distributions, and demand-supply graphs are common for tech candidates. Panels test whether you remember fundamental concepts from your academic background and can apply them practically.

Action Item: Revise: mean/median/mode applications, Binomial/Poisson/Geometric distributions with parameters, basic economic graphs (demand-supply, cost curves). Practice drawing graphs quickly.
3

Relate Work Experience to Business Impact—Not Just Technical Tasks

The questions on company differentiation and dynamic pricing show that panels want to see business awareness. Simply saying “I build APIs” isn’t enough—explain how your work creates value, improves metrics, or solves business problems.

Action Item: For every technical project you mention, prepare the business angle: What problem did it solve? How did it impact revenue, efficiency, or customer experience? Quantify where possible.
4

Be Ready to Explain Technical Terms in Simple Language

The “Is it full stack?” question shows panelists may not share your technical background. Your ability to simplify complex concepts demonstrates communication skills—essential for MBA group work and future leadership roles.

Action Item: Practice explaining your role to a non-technical friend. Avoid jargon; use analogies. “Full-stack means I work on both what users see (the website) and the behind-the-scenes processing (servers, databases).”
5

Use Examples to Ground Abstract Concepts Like Pricing Strategies

When discussing dynamic pricing differences between travel and airlines, concrete examples make your answer memorable. Abstract explanations get lost; specific scenarios stick. This applies to economics, statistics, and business strategy.

Action Item: For every concept, prepare a real-world example from your industry. “Our hotel pricing algorithm considers X, Y, Z factors—for instance, during IPL season in Mumbai, we see X% price increase due to demand spike.”
