Entretien
The interviewer was a recently graduated Ph.D and was really nice. We talked a few minutes on my resume and moved on to quantitative questions. He asked questions and let me do it with paper and pen. When I got a result, he told me whether I was correct or wrong. Anyway, the questions were difficult and I didn't pass

two phone screens. some interviewers were nice and others were more strict, lots of interesting math and research discussed. got asked a flurry of technicals, ramping up in difficulty each time, and even some open ended questions where they explicitly said there is no interview-tractable solution and just wanted to hear my ideas for an approach

HR phone call, tech phone call, then on site visit.
No food or breaks provided, pretty exhausting by the end when you meet with the manager who I would never speak highly about.

About 6 hours of 1:1 technical interviews with 5+ people in various domains (networking, database, programming, hardware).
A few phone interviews followed by technical chat with team member. Asked about past projects specifically, and followed by some questions that require a lot of working experiences to answer.
