Pfizer runs a fairly conventional big-pharma funnel: a recruiter-led HR screen, then one or more competency-based interviews (often a panel) built around the company's four core values, Courage, Excellence, Equity and Joy, with additional technical or presentation rounds layered on for scientific, medical-affairs and QC roles. Candidates repeatedly report long, sometimes silent gaps between rounds and lengthy end-to-end timelines, especially at R&D sites, and Ireland manufacturing hires (Grange Castle) note an in-person group interview and site tour for process-technician hiring.
These 8 writeups cover research and development, medical affairs, manufacturing quality and other roles, US + Ireland (Grange Castle) heavy. All of them were posted under a forum handle, so we could not verify the authors’ identities.
