Criteo Senior Software Engineer interview questions

I was contacted via LinkedIn by a recruiter. One Skype programming challenge followed by a 4 hour onsite interview. If you make it past that, you’ll have a single 45 minute phone call with an SVP. Entire process lasted 2 weeks before I had an offer. 4 hour onsite interview consisted of 2 one hour coding challenges, 1 design/architecture challenge, and 1 non technical interview with leads/managers. No NP complete or recursive algorithm question. Typical array/object manipulation questions. You’re expected to explain your algorithm’s time complexity. Overall I was very impressed with entire interview process.

1 Phone/Screen Sharing 4 Rounds of Onsite The recruitment team was super nice and probably the only silver lining in the entire process. The team was extremely rude so much I did want to walk out. I took up the issue with the co-ordinator during the break but seems like it backfired.The rest of the rounds were even more hostile where I clearly got the feeling that they ganged up against me once the recruiter voiced my concern.There was a small electronic gift which was given to me which I had left in the interview room during the break. When i come back, I see the gift was smashed on the ground trampled with feet.This is the height of nonsense and most unprofessional set of folks I have ever come across in my career.
