Pros
Garmin is an ethical company that care about providing good products and services to customers. They have good health benefits, so if you or a family member are sick or need maternity leave, they are a great place for that.
Cons
Promises or advancement opportunities were false, you have to work their 9 plus years before openings for advancement are options. Compensation is bellow market and raises are minimal or less than inflation so the longer you work their the more responsibilities they will give you with very little compensation. Product Support is left out of most decisions and are treated like second class workers. Marketing and Engineering don't associate with Product Support or ask their opinions. Marketing may do something that doesn't make sense and then leave it to Product Support to mop up the mess.
