Infrrd Java Developer interview questions

The Interviewer only know one approach of solving the question. If in case you have a better way of solving the question they will reject your solution as they don't know it .

I had attended interview there. I have written correct code on paper with mentioned time complexity. Second round was also great. In third round I run the code on Machine with correct output. After that I got rejected. I am not satisfied with given reason, if you are judging on particular question. If some one giving correct answer of 95 among 100 question, it is fair enough to select that candidate. We  have to fix a margin like 90-95%. I really very disappointed to go there.
