They were building a new site in Cambridge so they had the interview in Boston at a hotel. I waited in the lobby for the interviewers, who arrived in an elevator and then took you to be interviewed. Others also waited in the lobby to be interviewed. I was told there would be either 2 or 4 1:1 interviews, each about an hour. The interview itself was primarily what my experience was, followed by questions about things I had done, followed by coding problems. Then I was asked if I had any questions for them. I was already happily employed and would not have looked forward to driving to Cambridge. That day it took me 1.5 hours to arrive. Also I had read about carrying a pager here on glassdoor.com, and asked the interviewers about that. One said you carry it for a week every month; the next said you carry it for a week every 2 months. I was told at the end of my 2nd interview that there would be just 2 interviews that day. I responded, "That must be a bad sign" with the response that it probably wasn't a good sign. Sure enough I did not get the job.
