Complexity thinking and the linear structures everything builds on.

The patterns interviewers reach for again and again.

Trees, heaps, tries, and graphs — the onsite bread and butter.

Dynamic programming is the make-or-break topic for ₹30 LPA+.

The online-assessment round that gates most placements. Speed + accuracy.

Logical reasoning, verbal ability, and data interpretation.

What separates "can code" from "understands systems".

Concept clarity and trade-offs — the unlock for higher bands.

Depth in one language + real engineering habits.

The stack every product runs on.

End-to-end ownership.

How modern engineers actually work.

Projects that signal seniority — deployed, tested, not tutorials.

A non-brand-name profile has to make the signal obvious.

Reps convert — DSA rounds, core CS, project deep-dive, design.

Off-campus, discovery is your job — and leverage beats one interview.
