Well structured interview process. Enjoyed it and learnt a lot as well. First round was with the Talent Head who explained the process really well and made sure that I am clear about the process.
Second round was with their Product head, it was behavioural round. The interviewer was very polite and bring the best out of me.
3rd round was with the founder and it was more on how I think, what are company's objective and other general things
4th round was again with Product head. It was product sense round where one product design question was given. Evaluation was more based on the thought process and how structured it is rather than right or wrong answer.
Best part is that the whole interview process involved quick feedback loops. I loved that after each round, they asked for feedback from my side as well.
Talent head was prompt to reply about any doubts, rescheduling etc.
