I applied online. The process took 4 weeks. I interviewed at Pfizer in Feb 2018
Interview
It was just one phone interview with 2 interviewees- very casual and conversational, and low stress. It focused on a skill set that I haven't used since I was 16, and I was open about that and was still offered the position. Minimal technical questions, largely was just describing the project and answering any questions one may have.
