I have recently given the ZScalar Sr Staff Engineer and it was really bad experience.

They asked me DSA Hard leet code problem
A transformation sequence from word beginWord to word endWord using a dictionary wordList is a sequence of words beginWord -> s1 -> s2 -> ... -> sk such that, example

Input: beginWord = "hit", endWord = "cog", wordList = ["hot","dot","dog","lot","log","cog"]
Output: 5

I gave answer, explianed time and space complexity as well. It was failing because I did string matching in wrong way, somehow missed it. Otherwise 100% logic was correct.

Verdict : Strong No Hire

It was really bad that for 13 years experience folks they expect the HARD DSA problem and my interviewer was 7 years experienced only. The level of their immaturity was evidently visible

Interviewer was super rude, they did not turn on camera, however I was told to turn on camera, share screen too.
