7. What would you do if you were given a budget and materials to create a new product but were not given any limitations on what you could use?

Purpose: This tests your creativity, strategic thinking, and ability to navigate regulatory and practical constraints independently.

Response Example:

With unrestricted resources, I would begin by conducting a competitive analysis to identify gaps in the market, followed by an assessment of my company’s existing portfolio to pinpoint opportunities for differentiation. For instance, I might explore a dual-action oral care product combining antimicrobial and enamel-strengthening properties. I’d develop a base formulation, iterate through prototype testing—ensuring compliance with FDA guidelines—and refine it based on efficacy and safety data. This approach balances innovation with feasibility, maximizing the project’s potential impact.

8. How well do you work under pressure?

Purpose: Employers want assurance that you can thrive in a fast-paced environment while maintaining quality and safety standards.
