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

1 Dynamic Pricing in Travel vs. Airlines

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

Working in travel tech means understanding pricing strategies deeply—can you articulate the differences?

✅ Success Strategy

Key differences: Online Travel Platforms: Aggregate prices from multiple suppliers, add margins based on demand, use ML for personalization (user history, device, location), real-time competitor monitoring, longer booking windows (hotels), less perishable inventory (can sell rooms for future dates). Airlines: Direct inventory control, extreme perishability (empty seat = lost revenue), complex fare classes, yield management based on booking curves, shorter windows, regulatory considerations. Common: Both use demand forecasting, time-to-departure pricing, customer segmentation. Connect to your actual work: “In our platform, we use [specific ML models] for price optimization considering…”

2 Bitcoin and Its Creator

“Tell me about Bitcoin. Who started it?”

Tech professionals should know about cryptocurrency—both the technology and the economics.

✅ Success Strategy

Cover both tech and economics: Technology: Decentralized digital currency using blockchain (distributed ledger), secured by cryptography, transactions verified by miners through proof-of-work, limited supply (21 million cap). Origin: Created by Satoshi Nakamoto (pseudonym)—true identity unknown, published whitepaper in 2008, first block mined January 2009. Economics: Limited supply creates scarcity, price volatility due to speculation and adoption cycles, used as store of value and medium of exchange. Know key figures or pseudonyms behind major tech innovations—panels love testing this!

3 Central Tendencies and Their Importance

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

Statistics fundamentals are tested—but can you go beyond listing to explain context-dependent importance?

✅ Success Strategy

Three measures: Mean: Arithmetic average—best for symmetric distributions without outliers. Median: Middle value—best for skewed data or when outliers exist (income data, house prices). Mode: Most frequent value—best for categorical data or identifying peaks in distributions. Which is most important? “It depends on context”: For salary negotiations, median is better (skewed by high earners). For quality control, mean is useful. For market research, mode shows popular choices. The “right” answer is recognizing context matters—there’s no universal “most important” measure.

4 Discrete Distributions and Parameters

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

Probability distributions are commonly asked—know definitions, examples, and parameters.

✅ Success Strategy

Discrete Distribution: Probability distribution where random variable takes countable values (integers), not continuous. Examples: (1) Binomial: n trials, probability p of success—parameters: n (trials), p (success probability). Use: Number of defective items in a batch. (2) Poisson: Events in fixed interval—parameter: λ (average rate). Use: Website visits per hour, calls to call center. (3) Geometric: Trials until first success—parameter: p (success probability). Know at least 2-3 discrete distributions with parameters AND real-world applications. This shows depth beyond definitions.

1
Phase 1

Icebreaker & Profile-Based Questions

“Tell us briefly about yourself.”
Standard opener—structure is key
💡 Strategy

Structure: Education (B.Tech CS from NIT) → Work experience (1.5 years at online travel platform, key projects) → Motivation for MBA (career transition, leadership aspirations). Keep it under 90 seconds. For tech professionals, highlight both technical achievements AND business impact: “I developed [feature] that improved [business metric] by [X%].” End with why MBA to invite follow-up on your goals.

“Where are you currently working?”
Company details probe
💡 Strategy

Answer factually but add value: “[Company name]—it’s one of India’s leading online travel platforms, competing with [competitors]. We handle [X million] bookings annually for flights, hotels, and holiday packages.” Highlight the company’s market position, scale, or unique achievements. This shows you understand the business context, not just your technical role.

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

Focus on USPs: Technology (AI-powered recommendations, dynamic pricing), Customer experience (24/7 support, seamless UI), Partnerships (exclusive hotel deals, airline integrations), Market positioning (budget vs. premium, domestic vs. international focus). Example: “We differentiate through [specific USP]—our platform uses ML for personalized recommendations, and we have exclusive partnerships with [X] hotels.” Show you think about competitive advantage, not just code.

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

Clarify your actual role: “Yes, I work across the stack—frontend (React), backend (Java/Python), and database layers” OR “I primarily work on backend services using [tech stack].” Be ready to explain technical concepts for non-technical audience. If asked follow-ups, explain your role in business terms: “I build APIs that power our booking system, handling [X] transactions per day.”

2
Phase 2

General Awareness & Tech Questions

“Tell me about Bitcoin.”
Testing tech awareness beyond your domain
💡 Strategy

Cover both technology AND economics: Tech: Decentralized cryptocurrency using blockchain, transactions verified by miners (proof-of-work), immutable ledger. Economics: Limited supply (21 million cap), store of value vs. medium of exchange debate, price volatility. Current context: El Salvador adoption, institutional investment, regulatory debates. Balance technical explanation with economic/social implications—panels want to see holistic thinking.

“Who started it?”
Testing knowledge of tech history
💡 Strategy

Satoshi Nakamoto—a pseudonym, true identity unknown. Published the Bitcoin whitepaper in October 2008, first block (genesis block) mined January 3, 2009. Various theories about identity (could be individual or group), but never definitively proven. Know key figures/pseudonyms behind major innovations: Vitalik Buterin (Ethereum), Linus Torvalds (Linux), even mysterious ones. This shows you follow tech history, not just current trends.

Phase 3

Business & Analytical Questions

“How is dynamic pricing decided in your company?”
Testing business understanding of your domain
💡 Strategy

Explain the mechanism: “Dynamic pricing in travel uses multiple factors: (1) Demand signals (search volume, booking velocity), (2) Supply constraints (available inventory, competitor pricing), (3) Time factors (seasonality, day of week, time to check-in), (4) Customer segmentation (device, location, booking history). We use ML models to predict optimal prices that maximize revenue while maintaining competitiveness.” Connect tech to business outcome—don’t just describe the algorithm, explain the business logic.

“How is it different from airline companies?”
Testing industry knowledge comparison
💡 Strategy

Key differences: Airlines: Direct inventory control (own seats), extreme perishability (empty seat = lost revenue forever), fare classes (economy/business), yield management with booking curves, regulated pricing in some routes. Travel Platforms: Aggregate from suppliers (don’t own inventory), add margins, compete on service/UX, can offer alternatives (different hotels), longer booking windows. Common: Both use demand forecasting, competitor monitoring, time-based pricing. Show you understand business model differences.

“Draw the demand and supply graph.”
Testing basic economics visualization
💡 Strategy

If using paper/whiteboard: Draw X-axis (Quantity), Y-axis (Price). Demand curve slopes downward (higher price = lower demand). Supply curve slopes upward (higher price = more supply). Intersection = equilibrium (market-clearing price). Be quick and neat. Explain: “At equilibrium, quantity demanded equals quantity supplied. Shifts occur due to [external factors]—e.g., a new hotel supply shifts supply curve right, lowering equilibrium price.” Connect to your industry for bonus points.

Phase 4

Statistics & Quantitative Reasoning

“What are the central tendencies?”
Testing statistics fundamentals
💡 Strategy

Three measures: Mean: Arithmetic average (sum/count)—sensitive to outliers. Median: Middle value when sorted—robust to outliers. Mode: Most frequent value—works for categorical data too. Go beyond listing—mention when each is useful: “For income data, median is better because high earners skew the mean. For categorical preferences, mode shows the most popular choice.”

“Which one is most important?”
Testing conceptual understanding
💡 Strategy

The answer is: “It depends on context.” There’s no universally “most important” measure. Mean is best for symmetric data without outliers. Median is better for skewed distributions (salary, house prices). Mode is useful for categorical data or identifying common patterns. Example: “For average customer spend on our platform, we use median because some high-value bookings skew the mean significantly.” Show context-dependent thinking.

“What is a discrete distribution? Can you name one?”
Testing probability fundamentals
💡 Strategy

Discrete distribution: Random variable takes countable (integer) values, not continuous. Examples: Binomial: Number of successes in n trials (e.g., number of bookings that get cancelled out of 100). Poisson: Events in fixed interval (e.g., website visits per hour). Geometric: Trials until first success. Bernoulli: Single trial, success/failure. Name at least two with real-world examples relevant to your work.

“What are its parameters?”
Testing depth of statistical knowledge
💡 Strategy

For the distribution you named: Binomial: n (number of trials), p (probability of success). Mean = np, Variance = np(1-p). Poisson: λ (lambda)—average rate of occurrence. Mean = Variance = λ. Geometric: p (probability of success). Mean = 1/p. Know the formula, parameters, AND when to use it. Example: “We model daily cancellation counts using Poisson distribution with λ estimated from historical data.”

The most important lessons from this interview experience.

1

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

This 22-minute interview covered: company differentiation, dynamic pricing comparison (travel vs airlines), Bitcoin fundamentals, demand-supply economics, central tendencies, and discrete distributions. Tech professionals must prepare beyond coding—panels test business acumen and quantitative reasoning equally.

Action Item Create three preparation buckets: (1) Domain knowledge (your company, industry, competition), (2) Business/economics basics (pricing, supply-demand, market dynamics), (3) Statistics (distributions, measures, graphs). Allocate equal preparation time to each.
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 want to see that engineers understand business fundamentals, not just technical skills. Being asked to “draw the demand and supply graph” tests whether you can visualize and communicate economic concepts.

Action Item Practice drawing: demand-supply curves, normal distribution, histograms. For statistics, know not just definitions but when each measure/distribution is applicable. Connect to your work: “We use Poisson distribution to model daily booking cancellations.”
3

Relate Work Experience to Business Impact—Not Just Technical Tasks

Questions about your company’s differentiation and dynamic pricing test whether you understand the business context of your technical work. “I write code for the booking system” is weak; “I developed the pricing algorithm that increased conversion by 15%” shows business thinking. MBA panels want future business leaders, not just coders.

Action Item For every project on your resume, prepare a business impact statement: “This feature/system/algorithm resulted in [specific business outcome: revenue, efficiency, customer metric].” Practice explaining your work to a non-technical friend.
4

Be Ready to Explain Technical Terms in Simple Language

Questions like “Is it full stack?” and “Tell me about Bitcoin” test your ability to explain technical concepts clearly. MBA programs value communication skills—if you can’t explain your work to non-technical interviewers, you’ll struggle in cross-functional business roles. Jargon-heavy answers signal poor communication.

Action Item Practice the “explain to your grandmother” test for every technical term in your profile: full-stack, API, microservices, ML model, blockchain. If you can explain it simply, you truly understand it. Use analogies: “An API is like a waiter taking orders between the customer and kitchen.”
5

Use Examples to Ground Abstract Concepts Like Pricing Strategies

When discussing dynamic pricing or statistical distributions, concrete examples from your work make answers compelling. “We use ML for pricing” is vague; “Our algorithm considers 15 factors including booking velocity, competitor rates, and seasonality to optimize prices every 15 minutes” shows real understanding. Ground abstract concepts in specific, tangible examples.

Action Item For every concept you might discuss (pricing, distributions, algorithms), prepare one specific example from your work experience. Numbers and specifics add credibility: “Our dynamic pricing reduced unsold inventory by 23% during off-peak periods.”
