LinkedIn Data Scientist interview questions

45 Minute phone screen. Multiple one one meetings and a lunch interview in the cafeteria with at least five employees. Cafeteria was completely chaotic. Very difficult for the group to find seating together. Once seated was peppered with questions by everyone. Lunch should have been in a conference room if it was going to be part of the process. Overall not a very difficult interview, just was not well organized.

I was referred by a friend who is also a data scientist at LinkedIn. I had a one hour phone conversation with my friend's manager. The interviewer was nice and polite. Asked me two technical questions, one of which statistics and the other coding using an online platform. I haven't prepared at all before hard so didn't do well.
