There were 4 rounds and what I liked about the process that every interviewer was very friendly and made me very comfortable throughout
1st interview was technical including questions related to frontend and backend automation
2nd interview was a dev round where questions were related to Data structures and cloud services
3rd interview was with engineering manager where the questions were more of situation based where how to handle the team and test the product in different situations
4th interview was with hiring manager where we discussed about the challenges we face in QA teams and how we handle them
The whole process from scheduling first interview to releasing the offer letter happened in 4 working days
