    Advice to Management

    This is a great company to work for. It's not often that you can find a major, multi-billion dollar global healthcare business with international headquarters based here, in the heart of Chester County, PA. This company has a great business model in that it partners with all the major pharmaceutical companies. So, in terms of impact, its reach is far and wide. As an employee, it's nice to be a part of a business that makes such a big impact on patient lives. As a growing business, with a long history, there's a mix of both established employees, who have been with the company for many years, and lots of brand new employees too. When you meet people who have been a part of the company for thirty-plus years, you know you've found a company that's worth being a part of. New employees are bringing fresh thinking and newer ways of working to the table, and the combination of these two factors is creating positive change within West. There's also a real spirit of community at West. The work the teams do to raise money for local charities is impressive, and you can tell it's an important part of the culture. As the company continues to grow, management should continue to stay true these great cultural attributes, while they embrace new strategies that will help the company thrive in the future.

    Associate Packaging Engineer Interview

    Anonymous Employee in Exton, PA
    Accepted Offer
    Positive Experience
    Average Interview


    I applied through an employee referral. The process took 3 weeks. I interviewed at West Pharmaceutical Services (Exton, PA) in November 2019.


    I was working as a temp for West when my manager pointed me towards this role. However, I still had to apply as an external candidate. The interview process began with a short (about 30 min) phone call with an HR specialist, during which we discussed the details of the role and a bit about my background (very straightforward). Since I was already working in the same building as the hiring manager, I was able to skip the phone interview with him and move directly to the on-site interview stage. This stage consisted of 4 30-minute interviews, each with a different employee of West (director of division of R&D, director of packaging, hiring manager, and senior packaging engineer). During these interviews, I had to go into more detail about my experience and qualifications for the position, in addition to answering a few behavioral and technical questions. After completing this stage, I received an offer about a week later.
