It was an open house running from 4 to 7 PM. I was in a line where the to-be interviewee in front writes down basic information provided by MGH (e.i. your name, how you found out about the job, have you applied here before). After that process, we interviewees--where there was at least 50 of us in the first hour--were placed in the waiting room that consisted mostly of chairs and a video on TV describing the position. When I was called twenty minutes later, I went into a room where five other people had private interviews. The interview was pretty short (4 questions). The interviewer told me she's going to make calls in 2-3 weeks.
