I had two rounds of back to back interview. The first round is for resume, BQ and basic CS questions, the interviewer is friendly. The second round is really awful and I don't even feel like the interviewer wants to hire anyone. Below is the detailed process: I was given a problem that has a very complicated input format which will need a lot of dirty work in code. And I feel like it is kind of a combination of two questions which leads me to write about 70 lines of code in Java in a non-friendly IDE (codeSignal). The interviewer also seems to be not prepared for this question at all, she didn't try to explain to me about the question which the description itself is unclear and very long, it also has a mismatch between the function signature asking me to write vs the description of input and output. I asked several times and she just pointed me to the problem statement. The whole time of implementation she only gave me 30 minutes including writing my own tests cases, run the code and debug, starting from just showing the problem to me, which I feel like for a problem with so many complicated input structures (Four layers of a Java container which is very dirty) and write it at first time it's almost impossible to read, understand and write all the 70 lines of code in 30 minutes, not to mention the confusion the interviewer and the unclear problem statement costing me extra time just to make sure what it wants. I have to also complain about the interviewer since she doesn't seem to understand my code as she was wrongly accusing part of my code being wrong for the part of a Java 8 style sort with lambda comparator. She seems to barely know about Java 8 and told me that this part of comparator should return a String since that's what the problem is asking for while in reality the Java Comparator can only return integers. I have to also clarify about the interview timelines. We spent 15 minutes on the introduction part, then after about 30 minutes's coding I was asked to stop and not to write anymore. There are almost 15 minutes left for the one hour interview which not giving me any chance to write anymore. If the interviewer feels that she could do all the work first time getting this long question with so many confusions, then she must be able to implement this as a feature in daily work in 30 minutes including discussion with PM and writing unit test. Hopefully people seeing this try to avoid or be careful to interview with Zoom since they expect you to implement features in 30 minutes
