Nexsum is your AI‑graded practice gym for senior software engineering interviews. Drill what actually matters in minutes a day — so when that loop finally lands, you’re ready.
See how it worksFour categories, every question graded by AI, tuned to your stack.
Components, capacity estimation, the SD interview process, and classic scenarios — URL shortener, news feed, Uber matching, YouTube streaming, payments. Sketch the architecture and name the trade‑offs.
From common warm‑ups (“tell me about yourself”, strengths, why this role) to STAR‑format competency questions on conflict, mentorship, ambiguity, and ownership. AI grades against the signals interviewers actually score.
Processes vs threads, TCP vs UDP, ACID, SOLID, CAP, hashing vs encryption, idempotency, scalability — the fundamentals every working engineer should know cold. Concept clarity, not internals trivia.
Per‑skill batches for the languages, frameworks, services and tools you actually use. Languages get output‑prediction questions and language quirks. Services get high‑level concept drills on Kubernetes, Kafka, Redis, AWS and the rest.
