I got this interview opportunity through an agency. It took 3 rounds to complete and most questions are technical questions but more in a general way. overall it took around 2-3 weeks to get the final outcome. All the interviewers are very friendly and nice, the experience is much better than other companies I interviewed with. They spend quite a lot of time to give you a picture of what they are doing and make you understand better. 

Interview was simple and quick, Questions asked were straight to the point. They also take good notes and let you explain what you did previously. Was thrown with a question on the spot to promote us to think through and give an answer after. Overall a very good experience.
