Fast, causal. It was online. The interviewee was very straight forward with his questions, no small talks. Quick company intro. Only 1 round of interview. Interview result was very fast (got an offer the next day)

I had an on-site and online interviews where they asked general questions related to the role's expectations, my background, and my goals for the next few years. They also provided a take-home task, which was paid. Overall, the interviewer was okay.
