I applied in-person. The process took 4 weeks. I interviewed at Apple (Sunnyvale, CA)
Interview
There were two phone interview and an onsite interview with 5 interviews.
Mostly SQL. The focus is on aggregate functions, window functions etc. There were database design questions also. There programming and data mining questions also.
Overall it was a good experience. All the interviewers were nice. But at the end, the recruiter never told me the results of the interview. Even after mailing her multiple times. Did not expect this unprofessional approach from Apple.
Initial HR screen with basic questions about yourself and your background, followed by a technical screening round.
I was only asked technical questions; there was no coding round. I believe coding may be a separate round.

Assez difficile. Enormément de questions qui ont peu de rapport entre elle. Le recruteur était cependant très à l'écoute sur les problématiques métiers rencontrées lors de ce call. Merci à lui.
