First round is an online HireVue with behavioral questions and MC. The second round is 1 hr 45 min behavioral plus technical with two engineers. I'm not sure if that's the final round, though.

I interviewed with them 3 times for 3 different teams and got 2 out of 3 offers. I decided not to go through with them because I accepted an offer from a different company. The ones with offers had me answer mostly technical and behavioral questions

At the assessment centre, they went over the CV and the questions from the online assessment to ensure you did not cheat and could explain your solutions. There were two interviews, both "Technical".
