I applied through a recruiter. The process took 1 week. I interviewed at Criteo (Palo Alto, CA)
Interview
It started off with a phone call from the recruiter where we discussed about the role and my background. Next came a Skype interview with one of the engineers. That was followed by an office visit and 4 rounds of face-to-face interviews. Out of those, 2 rounds were purely coding and algorithms based, one was a design discussion on a large-scale problem and the final round was a manager's interview round.
The people over there are really pleasant to talk to and they even give you a bag with some Criteo goodies.
Interview questions [1]
Question 1
Standard questions based on Tries, Arrays, Hash Tables. Design round was based on key-value stores. Everything can be found in "cracking the coding interview" or on leetcode.
This has first round of HR screening and two rounds of Technical round (more coding discussing with interviewer) and one round of system design. Later last round of offer discussion.
