The best thing about working for Motorola Solutions is also a part of its most negative aspect: working for public safety customers. What this ultimately results in is having a very niche, very specific technical skill set. I work as an RF engineer within Motorola. After being in the same position for 6 years, I am in a state where I'd like to see what is next. For my very specific case, any other positions that are viable to me do not interest me. I enjoy what I do right now but I simply don't have the desire to work in the positions beyond what I'm doing right now. They simply don't interest me. If I look at opportunities that are outside of the company, and I want to continue living in the same location, there aren't too many positions available in other companies. I would very likely have to move in order to find a job that I'd be happy with. And I'm not ready to do that.
Keep in mind that my scenario is specific to me. My advice to anyone looking to get hired at Motorola is to be sure that positions available beyond what you'd initially be hired for are of interest to you. As you start to develop your technical skill set, then a lot of it will very likely only be transferable within other positions of Motorola or other companies that deal with public safety customers. You may possibly be able to work for cellular companies or an indoor RF communications company. However, the technical skill set isn't as close of a match. That's the story for RF engineers at least. If you're getting hired for software development, marketing, finance, etc., then I don't believe you'll be in the same situation. I can't confidently comment on that though since that is outside of my field. If you're willing to move to other parts of the US, then you'll also likely be okay as you'd be able to find other opportunities elsewhere more easily.
In addition, my salary is slightly lower than the national average. I have a Master's of Science in Electrical Engineering and my pay is slightly below the national average. However, I did not attempt to negotiate that when I was initially hired.
