I applied through an employee referral. The process took 1 day. I interviewed at ServiceNow (Hyderabad) in Oct 2020
Interview
Attended a virtual Interview process it not up to the mark.
I would humbly suggest company should train the interview pannel.
My experience was terrible; Interviewers was expecting a specific solution (One he knows/ One he looked up in geeksforgeeks) for open ended question.
- Interviewer does not understand time-complexity and suggested a worst performing algorithm would perform better than the solution I provided.
Please, Interviewers, if you are asking a question from geeksforgeeks or leetcode, atleast understand the problem well, maybe solve it yourself first!!

e.g. given by him
1010 --> 0010 --> 0011 --> ans = 2
00001100000 --> 00000100000 --> 0000000000 --> ans = 2
