The interview process consisted of one phone call and then a second round superday at their Boston office. I was interviewed by 8 people in total, including senior members, and the day lasted several hours. It was an overall pleasant experience and I liked the people there and got positive feedback. Very few technical questions were asked. However I have not heard back from them (and at this point do not expect to). They interviewed three candidates. I know it was a large capital outlay on their part to fly me in and put me up, but one would think it common courtesy to send a simple "we've chosen someone else" email, especially since they weren't interviewing a high volume of applicants.
