LinkedIn Senior Data Scientist interview questions

I had 2 technical phone interview and one on-site at their HQ. LinkedIn is a big company but the recruiting process is very disorganized. They have the worst recruiters I have ever worked with. Multiple rescheduling and they easily don't give you a call at the scheduled time. They need a big overhaul in their recruiting team.

The Interview process is very challenging but the interviewers are really nice. The onsite interview is a whole day interview composed of 6 modules. Almost all modules are composed of product sense questions.
