Awful. Red flags for a toxic work culture. I met 3 interviewers, all were exhausted. God knows what they were building. Completely drained and engrossed into their own world, asking theoritical to most difficult questions, kind of to reject you. And even if you pass, there is not a good vibe. They pay a penny and expect you to a coder, Ml researcher and Deep learning Gen AI architect working at OpenAI or Google Deepmind ! Shame on your process. No idea it was coming.
