Looking back, the interview experience was surprisingly smooth and straightforward. After a couple of technical rounds, I faced a system design question about building a low-latency alerting platform and a DSA question on finding the top-K elements in a sliding window. Funny enough, I recognized the latter instantly — it was the same problem I'd worked through on PracHub. Overall, the process felt easy, and I received an offer, which I ultimately declined to pursue other opportunities.

HackerRank 2 questions both were medium level even though i solved both i didnt hear back from them. i got rejected later on with no specific reason. Please tell me if someone landed an internship in citadel i want to know the further process.
