Pros
I just started with Thermo Fisher in February, and am enjoying my experience so far! In general, the company is very trusting and open to employees working remotely. Personally, I work from home 1-3 days per work, and the rest of the week, I enjoy going into the office to continue to build camaraderie among colleagues and hold in person meetings. Thermo Fisher also truly cares about employee development, training and mentorship. They are always focused on continuous improvement, and open to experimental ideas. They continually reiterate their mission of enabling customers to create a healthier, cleaner, and safer world which reinforces your purpose of why you're there and working so hard every day. My colleagues are extremely insightful, supportive, and open to ideas as well. And the flexibility in potential work locations is incredible since they are based all around the world.
Cons
You must be able to hold yourself accountable to your responsibilities and deadlines. It's fast moving, despite it being a large company, and they rely on entrepreneurial self-motivated, well-disciplined individuals to stay on track. Also, you need to learn very quickly. This is a massive organization and they are very spread out, so building a network, understanding available resources, and initiatives throughout the company will only improve your experience.
