I received a phone call from Merck on the east coast, and was asked a few basic questions about my research experience. At the end of the conversation we set up an interview time, and I was also emailed a few links that HR needed to be filled out. These were for the background checks they need to do. I then had the in person interview with 6 different members of the company. A department director, direct manager, and co-workers from that department. The interviewing took about 2 hours, and then the manager gave me a little tour around the building and showed me the lab space.
