It was a really smooth process and was over in about 5 days. I had a phone interview with my manager who was looking for an intern on his team. We discussed a bit about my background and the work they were looking for the intern to do at Glassdoor. There was one technical question following which he gave me a data challenge to solve (over the weekend but you're not supposed to spend more than a couple of hours on that). Following the data challenge, I had another interview with the VP of the B2B marketing team where we went through a case study. Within an hour of my second interview, I got a call from the HR notifying me of my offer. They really put the effort in to put you at ease and should be an example to other big companies who make prospective candidates go through all sorts of inconvenient procedures, not to mention over a big length of time (1-4 months).
