There was supposed to be one programatical round but they took 2 instead. In 1st round the interviewer kept adding different scenarios every now and then and it took around 1:10 hours for algorithm and then writing the actual program. I was able to solve it and I got another problem for which I just explained hm the way. So the total time was around 1:30 hrs for round one. HR conveyed me the status saying I was good but I was slow which I was ok with as well despite not getting all the scenarios in advance. So they said they will have another round. In 2nd round I was asked a tree problem. This time I asked for all the scenarios in advance. Initially I didnt understand the problem and I asked if he wanted me to print all leaf nodes. The interviewer surprisingly didnt know what leaf nodes were and he had asked me a tree problem. When he explained what he wanted, I was able to solve the problem which was a medium level premium leetcode problem in 45 minutes. But again, I was told I was slow and they rejected me. I was sure I would go through this round but I dont know on what basis they judged me. It was a disappointing interview overall. Both the interviewers themselves were not prepared and they had over 12 and 16 years of experience respectively.

Stupid interviewers in panel. They are not hiring s/w engineers, they hiring leetCode engineers. As it is problem from leetcode of Hard level. Interviewer don't want to hear other approaches only want to hear what he knows. No project knowledge and technology related stuff needed. If you are really doing great work then come up with your own problems.
