Merck.

Keytruda is the world's best-selling drug, generating over $25 billion annually and approved across numerous cancer types. It represents a substantial portion of Merck's revenue. The company is actively preparing for Keytruda's loss of exclusivity through pipeline investments, subcutaneous formulations, and next-generation immuno-oncology combinations. Understanding both Keytruda's importance and Merck's diversification strategy shows you grasp the company's central strategic challenge.

Merck Research Laboratories (MRL) is one of the largest pharmaceutical R&D organizations globally. The culture values scientific rigor, data-driven decision making, and intellectual honesty about what the data shows. Merck has a strong tradition of publishing research and collaborating with academic institutions. The company makes significant R&D investments as a percentage of revenue. For research candidates, demonstrating both scientific depth and the pragmatism needed to advance drugs through development is important.

The Merck interview process typically includes an initial recruiter screen, followed by one or more technical or behavioral rounds, and a final on site or virtual loop. Each stage evaluates different skills depending on the role you applied for.

Feedback timelines vary by company and team. As a general rule, expect to hear back within 1 to 2 weeks after final interviews; if Merck has not responded after 5 business days, a polite follow up with your recruiter is appropriate. Orbyt can help you track follow up timing automatically.

Many Merck roles include a technical component, though the format varies. Engineering roles may involve coding challenges or system design, while other positions focus on case studies, portfolio reviews, or domain knowledge assessments relevant to the team.

Merck interviews typically blend both behavioral and technical elements. Most loops include at least one behavioral round focusing on past experiences and one technical round assessing domain skills. The exact split depends on the role, team, and seniority level.

Strong Merck candidates demonstrate both technical competence and alignment with company values. Prepare concrete examples of past impact, show curiosity about the team's challenges, and ask thoughtful questions that reveal your understanding of the role and company direction.
