Pros
The best thing about Garmin is the generally friendly attitude among the employees. Managers and employees are eager to share knowledge across teams. It's not uncommon to have face-to-face discussions with the other people working on a project. There's a definite focus on problem-solving and creating better products. Company provided benefits are acceptable, and other amenities such as on-site gym are a plus.
Cons
The leadership among management seems hit or miss. Some are very interested in the well-being of their team, good at communication, or have a vision for products, while others are lacking. This has created confusion or frustration among employees about projects ("What are we doing? Why are we doing this?"). Sometimes management seems isolated, or lacks "big picture" thinking.
