Hiring Speed, OA Formats & Ghosting Intel

Delivery routing questions frequently re-appear as modified Dijkstra or Multi-Source BFS. Don't write recursive DFS without memoization — hidden test cases trigger stack overflows.

Zepto interviews move faster than anyone else in Bangalore right now. You can get from OA to Offer in under 12 calendar days if you score >90% on Codility.

BrowserStack focuses heavily on low-level system understanding. Expect questions about how browsers establish TLS handshakes and WebSockets multiplexing alongside classic DSA.

Round 2 machine coding round requires writing functional, runnable code in 90 minutes. Practice structuring object-oriented design (Snake & Ladder, Splitwise, Rate Limiter) with clean interfaces.

Flipkart machine coding round is legendary. You will be evaluated on extensibility, clean code, unit test coverage, and design patterns. Never hardcode logic into a monolithic class.

CRED recruiters value exceptional craft and high taste in software. If you have built audited microservices or open-source libraries, highlight them directly to skip round 1.

Atlassian tests your behavioral values ('Open company, no bullshit') as deeply as your code. In tech rounds, talk through trade-offs constantly — silence during coding is heavily penalized.

TCS National Qualifier Test (NQT) places immense weight on aptitude and verbal accuracy before touching coding. If you fail the numerical ability section, the coding test isn't even graded.

Specialist Programmer (SP) OA is surprisingly tough with 3 DP/Graph questions, while System Engineer (SE) is mostly aptitude. Passing 2 out of 3 SP questions guarantees an interview call.
