The interview process was straightforward. Applied on Pfizer website, technical recruiter reached out the following day to schedule a preliminary phone conversation. The conversation was about 20 minutes long. The purpose of the phone call seemed to be determining my level of interest in the job, need of H1B visa, relocation needs. The recruiter went over the job and talked about the work site. He asked a couple questions about my technical experience. About 5 weeks later, the hiring manager scheduled a WebEx meeting with me for the following day. It lasted about an hour. The conversation was about mainly about the technical aspect of the job and how my skills could fit in. The conversation was closed with an invitation to do an "onsite" interview (WebEx due to Covid policy). A week from that I interviewed via WebEx, and a week after that I accepted an offer. Total time from application to accepting offer was about 6 weeks. The WebEx "onsite" interview was about 5 hours long. It had the usual structure of chatting with the hiring manager and his colleagues. I presented a 45 minute seminar on research I'd done. Conversations with the team members were 25 minutes long, with a 5 minute break between sessions. The WebEx "onsite" interview was well planned. The only problem I ran into was poor quality audio during a few sessions. The audio quality seemed to be the worst when three interviewers were sitting around a laptop talking with me. No idea what the problem was but I hardly understood anything they were saying to me. I had to ask them to repeat themselves multiple times and often still didn't know what I was being asked. Thankfully they knew the audio quality was very poor on their end. A couple conversations in which solo interviewers were using bluetooth headphones also had audio problems. The sound seemed to keep cutting out when they were speaking.
