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 ....
