Applied for a Java backend position. The interview consisted of three rounds. All three rounds were taken by vice presidents.

The first two rounds, the questions asked were general software concepts and algo/ds. These two interviewers were serious enough for the interview. The first two rounds went really good.

I had bad luck with the third person. He was an older guy (but still at a beginner level designation). All the time, he was busy checking his messages and doing some work on his laptop. I wonder if he was listening to my words at all. He was like, 'Ask a question' -> 'Hmm,' 'Another question' -> 'Hmm, hmmm.' Lol. Dude, either you should take the interview or do your own work; don't mix things up. It is not fair to the candidate.

He was asking knowledge-based Java questions. He was not motivated enough to tell the complete question. Then, when I gave the answer, again 'hmmm.' Lastly, he asked me to tell new features of Java 15. Lol, dude, I'm not sitting idle at my home reading release notes of every new Java version that gets released. I told him politely that I can only answer for the Java version being used in my current organization.

At that moment, he finished the interview with another 'hmm.'

I felt sad having wasted time interviewing with these people.

Make sure you have read all the release notes for every new Java version that is released.

Also, try practicing what 'hmm' means for JP Morgan employees.
