1. HR phone call Then I had 3 interviews, including coding, system design and some behavioral questions HR called to say that I've passed and scheduled a AA interview with a manager. THAT WAS THE WORST INTERVIEW EVER! The interviewer behaved very unprofessionally – he even had his feet on the chair or on the sofa, the manner was extremely disrespectful. He asked me to implement a timer without using a built-in timer, which was a strange and confusing question, especially after I had already passed the LeetCode-style and System Design parts of the interview. The level of the question was unusual; he expected me to figure out that I could use a now() function across different departments to implement the timer. It was something I had never encountered before. Overall, it was a very unusual and uncomfortable interview experience.
