Thermo Fisher's loop is long and consistent across role families: a recruiter phone screen, a hiring-manager technical or scenario round, then a multi-person panel, often followed by a site visit or role-specific demo before a final decision. Commercial and account-manager roles pivot on a scripted equipment/software demo. Scientist and data-researcher roles include a take-home or timed skills test and a rigorous review of that work. PPD (clinical) roles run a separate but similar recruiter, hiring-manager, then panel funnel with heavy emphasis on prior CRA experience and travel/monitoring scope. Candidates repeatedly report slow feedback, opaque pay ranges, five-round loops, and a strong internal-hire preference.
