It was an off-campus drive. I received an email from their HR with the requisite details. Then there was Round 1, an elimination round, which consisted of two coding questions: one DP and one graph problem. The difficulty was somewhere between moderate and hard.

Somehow, I cracked Round 1. After that, there was a technical interview. I could not clear the cut here, basically due to my nerves. Although I knew the questions, I couldn't explain them properly. It might have been my branch (non-CS/IT/ECE), but I should have been calm.

Round 1: Modified LCS and DFS-based question.

Round 2: Running median of an array, invert binary tree, and some more questions.

How will you find the running median of a stream?
