I declined moving forward in the interview process. For more info, please read below. Started off with a meeting with a recruiter. She described the role and how I could fill up this. Next was a 1 hr interview with the hiring manager. It started off with a "tell-me-about-yourself" followed by a series of technical questions over full stack. There were several red flags I noticed during my turn of asking questions at the end. 1. The team was clearly siloed and perhaps this team is not open culture. It appears its going to be hard to collaborate with the tech leads since they are long timers. 2. Responsibilites for senior/principal appears is negligible compared to the tech leads. 3. The interviewer was clearly not interested with my background besides it was full stack (python). He mentioned this is a nice to have, but it turned out he made his decision in the first 10 mins. 4. Legacy tech - for various reasons I cannot disclose them but most tools (version control/CI) used here are very legacy. 5. Non-cross functional teams - Engineering teams are filled with devs only. For the above reasons I declined to move forward.
