Fly out interview to their office in Framingham, MA. Interviewed with 4 engineers on the team and the manager. First interviewer asked me about analog domain questions, then lunch with another engineer on the team, third person was the manager and asked me more behavioral kind of questions and 1 DSP question. Last interviewer was not a native english speaker with a thick accent, so it was a little hard to communicate, but he asked me about a project on my resume.
