First interview went ok. Second interview scheduled in the next month which was late enough, however before one week, they pushed it another month forward. Take it or leave it. lol That's alone is a red light, but I attended anyway. Soon other minor red lights appeared as well, like the general non-serious tone of the interviews.

It was a smooth process. The first interview was a technical round. Some standard question about ML and feature engineering were asked. The second was a task. A simple ML task was given with sufficient time. The last round was a discussion with the HR and the team lead.
