The interview process was very quick. I applied and was hired in a matter of three weeks - crazy fast. It's also a very detailed process. They gather a lot of detail to understand who you are and whether you'll fit with the culture.

Interview process was difficult. About 4 rounds, final round was a case presentation. The first few rounds were difficult but were pretty straight forward. The final round was more of a group panel which made it slightly more difficult than the previous rounds.
