After going through the phone screening, I was invited to an interview with the manager of a team. They rescheduled several times until they finally found someone to interview me. Unfortunately, the interviewer was very quiet on the mic and I could barely hear him. It also didn't help that he had a very heavy accent, which at one point I was afraid of asking him to repeat sentences out of fear of being rude. I was asked several tree questions, but unfortunately I could barely get through one because it wasn't clear what the interviewer wanted until he explained himself better at the end. Was also coding without an IDE and straight on a notepad...
