There were a lot of notorious questions, they tried to deep dive into every single aspct in the technology whoch was too much, and I did not like the process. I would not agree to go through this tech interview again
They wrote me questions about how I see the work and same, I put answers, then they disappeared for several weeks. Then back with the apologies. Asked again questions, I answered and they again disappeared and like for several months they did not answer. The interview was in chat.
