Pros
I am very happy that I worked for Annapolis Micro Systems. I learned a lot during my years here. Since I left the company I have had the opportunity to work with boards manufactured by a number of different vendors. I believe that Annapolis Micro Systems manufactures some of the best products in the industry. One of my favorite things about working here was my coworkers. The engineers here are great. They are all very friendly. I think you could ask anyone of them for help and they would be happy to do what they can to help you or teach you what you need to know. They are a great team to work with. Every engineer I knew was very good at their jobs. I think they had to be. It's not a very big company, so everyone has to be very good. If you accept an offer from Annapolis Micro Systems (As an engineer at least) you will always have work to do. They work with a lean team. Work / life balance is very good. You will be expected to a lot of different kinds of work. If you're an engineer you will be working on software, hardware, testing, ... You'll get to work on a variety of things that I don't think a single person would get to work on very many other places.
Cons
No company is perfect and Annapolis Micro Systems is no different. I loved that Annapolis Micro Systems was a small company. It makes you an important part of a small team. It's also a big problem. After a while you realize that there is almost no turnover on the engineering team. That's great for the company as a whole but it leaves no room for growth. The management team isn't going anywhere. They aren't hiring more junior engineers. They don't offer additional training. After a while there really isn't any more room for additional growth. That's why I ultimately left. I loved working for Annapolis Micro Systems and would work there again but ultimately decided that in order to continue to progress in my career I had to go somewhere else.
