Pros
Well-regarded company with good technology. The big leaders in technology come to ADI to ask them to work on stuff. Good work-life balance. Supervisors are largely understanding of personal issues. Relaxed environment but professional. You need to deliver on your work. No free rides.
Cons
To dispel previous comments from others: There is no "annual layoff". There is a two-week shutdown in last two weeks of calendar year but most days are holidays. Generally requires 2-3 days of vacation for that period. There is management entrenchment and advancement can be difficult beyond a certain level, depending upon situation. Below the senior level, you can advance rapidly. Salaries appear to be a bit low, annual merit increases are small. The upside in compensation is largely based upon the bonus plan, paid semi-annually. On the other hand, the bonus is good and the 401k match is too. Communication from management could be better. Some develpments are just not talked about openly. Capital spending is the first thing to be cut if there is even a hint of slower sales. Difficult to read the changes in wind direction on this ahead of time.
