Karat interview is LAME. I am a .NET developer, but I can hold my own in Java with a little practice. I mentioned this to everyone involved. I get to the Karat interview and I get close to an 8 minute explanation of the programming problem and I have 30 minutes to solve it. During those 30 minutes, you have to explain everything you are doing while you are typing. Talk and type 100% of the time. Sorry, I just cannot do that. When I would stop talking, I would get a threatening remark from the Karat person telling me he can "write me up" for acting suspicious if I don't tell him exactly what I'm doing. Just completely harassing and unnecessary. I asked a question about the web based IDE and if I can create a separate class file, but the guy didn't even know!!! Turns out, the guy didn't even know Java (he said this later)!!! Since I am a .NET guy, I had to remind myself how Java handles a collection, so I even pasted in an exact code snippet into the environment and I got a syntax error in that IDE. As to the question, it wasn't technically difficult but it did require several nested loops and flags to be set. Perhaps I could have done it better with more than 20 or so minutes, but while trying to figure out an IDE I've never used and having a guy constantly snapping at me to be talking, I just lost any interest in this position with about 2 minutes left in the interview. PayPal is supposedly a powerhouse in fintech, but they farm out interviews to people that don't even know the language they are judging competence.
