Pros
The benefits are excellent, positions tend to be flexible, job growth is not forgotten, pay is good, plenty of non-work events, easy to get equipment, stable job (for the most part). Overall, great working environment.
Cons
Qualcomm chipsets power a huge range of devices in the worldwide market. In order to stay competitive, the pipeline is always filled to the brim. This means that there's very little time for good software practices and much of the effort, at least from a SW perspective, is spent porting and patching. This gets tiresome after a while and doesn't provide for much satisfaction with one's job as actual innovation often needs to take a backseat. In addition, because there are so many engineers involved, getting things done is often difficult because there's always some team you'll need to get support from in order to get the job done, no matter how simple the task. The overhead is exhausting.
