I applied through Box's website and also had an employee recommend me from inside the company. I first had a phone interview with someone from their HR department. Basic questions were asked including walking through my resume, why I would be a good fit for the company, why I was interested in Box, etc.
Then I was set up with a second phone interview to speak with the VP of the department. More basic questions were asked, and a few more in-depth questions were asked, including a question on how I would go about analyzing the results of customer service surveys. The main "case study" question I was asked was basically "We have surveys that allowed answerers to rate their satisfaction with Box on a 1-5 scale, and we have surveys that allow answerers to rate their satisfaction with Box with a Yes or No. However, the results of these two surveys do not seem to be related. Could you provide any possible insight into why these two survey types do not seem to necessarily be correlated to one another?"
After this, I was set up to meet for a group interview in person. They call it "Oobie" ("Out Of the Box Interview Experience"). The five candidates that they were interviewing for the position all met at the same time for the group interview. It was unusual and a little intimidating to be able to see your competition face to face. It was round-robin style interviewing with five interviewers and interviewees. Each candidate met with each manager, one on one, for about 15-20 minutes, and then moved on to the next. It looked a little like speed dating. The process definitely moved quickly, but I felt that I wasn't able to really go in-depth with any one interviewer regarding my fit for the position. I had to keep re-telling who I was and my background to each of the five interviewers as they came around, which got to be exhausting near the end. They pretty much all asked the same basic questions, but in a different way - I wish they would have coordinated with each other beforehand to make sure they all asked different questions. Each of the mini-interviews were cut short at the end and I wasn't able to ask all of my questions after they were finished answering theirs. I left the interview with my head spinning.
I kind of felt like the round-robin interview style was a way for them to cut corners, speed up the interview process, and fill an opening, but it did not really give the candidates a chance for a full interview. It was stressful meeting 5 new interviewers separately, and it took a few minutes to get a read on each new interviewer to figure out their style, which cut into each 15-20 min interview significantly.
