Interview examples
Real questions, real answers.
The questions hiring managers actually ask in software engineering, consulting, banking, and quant trading interviews — answered the way senior interviewers want them answered, with the math, the structure, and the follow-ups every round inevitably surfaces.
Behavioral
Software Engineer Behavioral Interview Questions
Behavioral interview questions software engineering candidates actually get at FAANG, hedge funds, and quant trading firms — with sample STAR answers, what each question is really testing, and common mistakes that flatten the score.
Coding
Coding Interview Questions
The coding interview problems FAANG and hedge-fund interviewers actually use — bucketed by pattern (sliding window, two pointers, BFS, DP, heaps), with worked solutions, complexity analysis, and follow-up traps.
System Design
System Design Interview Questions
The system design prompts senior interviewers actually ask — design a URL shortener, a rate limiter, a news feed, a chat app — with the framework, capacity math, and trade-offs that separate a senior signal from a junior one.
Consulting Case
Consulting Case Interview Questions
Real consulting case interview prompts from McKinsey, BCG, and Bain — market sizing, profitability, market entry, and M&A — with the structure, math, and recommendation that win the case.
IB Technicals
Investment Banking Technical Questions
The investment banking technicals interviewers ask in every M&A and DCM round — accounting linkages, valuation, M&A accretion/dilution, LBO mechanics — answered the way bulge-bracket analysts answer them.
Quant Trading
Quant Trading Brainteasers
Brainteasers and probability puzzles asked in quant trading interviews at Jane Street, Optiver, Citadel Securities, IMC, and SIG — with the EV math, Bayesian setup, and market-making logic interviewers grade against.
