I applied online. The process took 4 weeks. I interviewed at Merck (New York, NY) in Oct 2016
Interview
1 hour phone interview, pretty straight forward.
Most questions are about research experiences and publications. So you can just be yourself and answer these questions from your CV. The interviewer does ask a couple of questions about a particular paper, but nothing tricky. No behavioral questions.
Interview questions [1]
Question 1
What is your research experience? Do you know how to use instruments, such as HPLC?
