Merck's hiring loop is a fairly standard big-pharma funnel: an application review, an HR/recruiter phone screen, one or more hiring-manager conversations, then a panel or a series of team interviews, plus a presentation or technical assessment for scientific, clinical and data roles. Candidates repeatedly describe long silences between stages, a candidate questionnaire sent through Workday after later rounds, and timelines that stretch to two months or more. Format and specifics vary by function and site (Rahway/Cambridge R&D, West Point/Dunboyne manufacturing, GCTO clinical operations, Philippines shared-services, India tech via MSD).
These 11 writeups cover r and d scientist, clinical research, medical affairs and other roles, US + India MSD + Ireland + Philippines. All of them were posted under a pseudonym (Reddit, GeeksforGeeks or forum handles), so we could not verify the authors’ identities.

Merck’s official process
MSD's own careers site describes a three-step journey: application (submit resume online, Talent Acquisition review, email confirmation), interview (an initial call with a Talent Advisor about the role and career journey, then either a direct hiring-manager conversation or a panel/series of one-on-one interviews, virtual or on-site), and offer. The company explicitly notes that AI-generated interview responses are discouraged so the assessment can reflect the candidate's own strengths, and asks candidates to keep in touch with their Talent Advisor since business timelines can slip.
A take-home-style technical assessment covering data-engineering fundamentals; the candidate finished it in a single sitting before the live interviews were scheduled.
