IndiaPosted Jan 2026 · Candidate report, summarized by Dataford

My first technical round was a DSA-focused session where I worked on a heap-related problem with time for optimization—specifically thinking about space and time tradeoffs while writing the solution.

It was structured like a timed coding interview, about 45 minutes, and the interviewer also asked whether I could do it in Go; I solved it in Python instead.

It felt like a fairly direct test of standard LeetCode-style reasoning with some emphasis on refining the approach rather than stopping at the first working solution.

Even though the difficulty landed in the average range for me, I didn’t end up getting an offer, and the overall feel was that it was a clean, structured evaluation but not necessarily something that guaranteed success.
