First interview is diveded in three parts plus a test. First you have to talk about yourself, then solve a case and then you can ask questions about the company. Afterwards you have to do a numerical test. The test is standard, you can find this kind of tests all over the internet.

2 rounds 2 cases each round; managers/principals in round 1 and partners in final round. Was overall quite a fluid process with clearly communicated timelines and expectations for the cases including time and structure
