Company guide
Cognizant GenC interviews are heavy on coding fundamentals and project ownership. Experienced roles add a client-account and domain layer.
Why they ask: Generic definitions get cut off; they want your code.
How to answer: Give one class from your project per pillar — inheritance, encapsulation, polymorphism, abstraction — and say what it saved you.
Why they ask: A breadth check — how far you can go before you run out of depth.
How to answer: DNS, TCP/TLS, HTTP request, server response, render. Go one level deeper on the layer you know best.
Why they ask: Tests real-world instincts over textbook knowledge.
How to answer: Logs and monitoring first, then narrowing by environment difference, data difference and timing. Mention rollback as an option.
Why they ask: Cognizant's managerial round is looking for initiative signals.
How to answer: STAR with something small and concrete — a broken script you fixed, documentation you wrote that others reused.
Why they ask: Anchoring. Answer badly here and you lose money before the offer exists.
How to answer: Give a researched range based on role, location and your experience, say it is negotiable for the right role, and ask for their band.
