The interview process was quite standard. I signed an NDA, so I can't say much, but nothing too exotic.

The experience was negative because the interviewer kept interrupting me all the time with questions that were not relevant at all.

Usually, in these interviews, you discuss the problem and possible solutions. Once you have a solution that you've agreed on, then you implement it.

It's also normal for the interviewer to ask questions if they think there's something wrong or if they don't understand something, but here it was constant and for things that I didn't consider reasonable.
