ServiceNow Sr. Software Engineer interview questions

There are total 4 to 5 rounds. After cleared my 1st round on DSA and algo. The 2nd round experience was worst and the interviewer was very rude it seems he already decided that he will reject the candidate and trying to show that he knows everything. In 2nd round the interviewer directly reject the solution without go through the code which I have written. When I asked the same he said the assign boolean array will have the garbage value ( he don't know that the default value is false when boolean array initialise in Java). Then i explained him it doesn't contain the garbage value. After that he said I have some duplicate condition in base case and i explained the case where we need it. It seems like he opened some code solution in his laptop and was expecting the same solution. Just because of that he was not trying to understand my code logic and Algo. I was surprised that in well established organization at higher position there are some people like this ....

Please do not waste your time on interview process with ServiceNow. I had 3 rounds of interview. First one was managerial. 2nd one was technical and 3rd one debugging round. Mostly on easy Concurrency and DS level. I had cleared all the rounds and got a call from HR that final round of interview would be scheduled for 2 hours. Then they tried to hide from me, started ignoring my calls. Finally I was able to talk to the HR and surprisingly said that my coding round was not good so I was not selected. And I could hear the vibration / hesitation of lie he is just making up. I clearly told him not to waste the time of candidates if you can't afford to hire one.
