EPAM Systems Sr Software Engineer interview questions

I had cleared the initial round and next was online Teams round . —The interview was scheduled in 30 mins immediately after calling. —The interviewer directly started with questions of Java 8, spring ,DS -I was able answer 70% of the questions -Interviewer never acknowledged if I was right or not (I didn’t expect ) but when the answer was wrong or not satisfied. He was taunting like “Oh you have not worked on this” Almost 10 times in interview this word was used when morally takes us down -Interviewer was googling n asking questions .so he was expecting google answer but not the conceptual knowledge -multiple question was asked on Linear list -pseudo code was asked for 2-3 programs which I was able to answer -multiple theory questions was asking on spring If couldn’t answer completely but if I would attempt to answer then sarcastic comment which took me down -he gave some program and ask to give optimised best solution in 15 mins But after starting after he 2 mins he would intervene and he was asking this approach is not optimised and asked to use some other approach I was not allowed to complete my approach Atleast .i might be give right or wrong or less optimised solution but anyone interrupting will definitely distract u At 14th min he gave some hint and when I start implementing he said time is over It was very uncomfortable interview though questions were good I don’t think interviewer should be sarcastic or taunting while taking interview Overall it was a poor experience though I learned abt my strengths Suggestion- if someone is not able to answer doesn’t mean he don’t know anything.please avoid sarcastic comments
