I applied through college or university. The process took 2 weeks. I interviewed at LinkedIn (San Francisco, CA) in Jan 2015
Interview
Contacted by recruiter after applying, and scheduled a phone chat with recruiter. Following that, the recruiter set up a phone interview interviewed with someone in the group. This process took about 2 weeks. Next stage seemed to be a day in the office interviewing with more members of the team.
Interview questions [1]
Question 1
Where do you see yourself in 5-10 years? Why LinkedIn? What do you want out of your summer?
