Perk Software Engineer interview questions

Hands down worst interview I have ever had. The first technical test was fine just basic questions. The second test was supposed to be a screen share code challenge. When i arrived the interviewer asked to see my prepared API which I didn't have, the email confirming the test didn't tell me to set up anything beforehand and i checked spam but got nothing so I had nothing to build off of. The interviewer then proceeded to rush the test and push me to make an APi but kept saying oh don't actually make the file structure and don't worry about interfaces etc and just make it functional. I was going to leave the interview but as someone had referred me I didn't want to make them look bad. Even though rushed I finished the API and described to him the preferred way of doing it. The response was, "the code structure could have been better organized" and rejected. Obviously it could've been better organized but he said just make it functional because we don't have time. Terrible way to interview. If the interview isn't prepared then reschedule and let me build something robust, don't decide to rush it.

It was a great thorough interview with interesting questions. However, I lost momentum at the system design interview due to a rude engineer on the interview who told me "thinking is encouraged, please think". He is from LATAM and works at the London office.
