Started off with a 25-question video interview (basic stuff - strengths, weaknesses, how to handle disagreements, etc.). Then brought in for a panel interview (just me and 2 others) which was very relaxed and informal. They wanted to make sure I understood the job responsibilities, travel requirements, and whether I would be dedicated to the company for the long-term.

I applied online. Then you have to do an online questionnaire regarding your personality. There was then a recorded webcam interview where you had to record yourself answering questions. Then a phone interview which was more like an interrogation if you ask me. Then if you pass the phone interview, they would invite you over to their Waltham office for an interview with a panel.
