Had a technical interview with a senior engineer. The interviewer was 10 min late to the interview and asked me questions about my resume and technical knowledge. After I failed to answer some questions due to my experience level, he turned very rude and condescending throughtout the interview. At the end of interview, I asked him what do you like working here and he said smart people and the people who left the company usually joined FAANG and don't work on boring stuffs like other companies do.
