It takes 3-4 rounds of interviews along with coding tests. The first round is with the HR who I believe tries to identify communication and attitude. The second round was the founder. He is technical but does not gruel you too hard. The third round was a 1:1 phone with a technical lead. This was very technical which ends with a coding test. The last round was another 1:1 in person meeting which was technical as well as personal.
