The interview lasted about 2.5 hours. There were about 8 people interviewing at the same time. As a group, we were greeted by Mike, who was very nice and helped make a relatively stressful process seem less daunting. He discussed the company for a bit and answered questions. Engineers came in and the VP(?) came to talk to us more about Monster. After that we each were paired with two engineers who interviewed us separately. It was more of a conversation about past experiences than a test of skills--as far as interviews go it was not bad at all. There were no curveballs. After some initial awkwardness on my part I think it developed into a pretty nice conversation. Overall it was a good experience.

I am a first year PhD student in Mathematics. I was looking for an internship related to data analysis and/or mathematical modeling. I handed in my CV at a school career fair. The representative told me that he would refer me to the data science team. A few days later, I received an email asking me to schedule a time for phone interview. The interview was about 20-30 min. Mostly, the questions were related to my past experience. I feel like they were just trying to get an idea of what my experience level was. The phone interview also contains some standard questions such as "why do you think you are a good candidate for the internship" and "what was the most difficult part of your experience at xxxx and how did you overcome it." After the phone interview, they moved me to the final round, which is on-site interview. At the end of March, I went to Monster's office in Weston, MA for the on-site interview. First, we were given a short tour of their new building followed by information sessions given by the HR and people from the engineering department. During the session, they asked us why did we want to apply for the internship. I don't think it was considered a formal question as part of the interview process. But people who were going to interview us were also in the room listening to our answers. Then we moved on to in-person interview. I was interviewed by two people from the engineering team, one of them was the person who phone interviewed me. It was not a technical interview. Nothing very technical was asked. They were trying to figure out what I want to get out of the internship and tried to match me to a suitable position. They also asked about my past experience in more details. The most difficult question was: give an example of a correlation you can draw between two categories of data that Monster collect. They gave me an example: suppose Jack was applying to Job A. Mary, who applied to Job A also applied to Job B. So it is likely that Jack would also want to apply to Job B.
