The process took 1 day. I interviewed at Janssen in Aug 2015
Interview
Very relaxed interview. Interviewed by almost a dozen employees, but the questions were not extremely difficult. A few mathematical questions, but it seemed they just wanted to learn more of my thought process as opposed to coming up with the right answer.
Interview questions [1]
Question 1
If I asked you to make me 350 mL of a 0.5M solution of NaCl, how would you go about preparing this solution? What information would you need to know?
