Pros
Great growth opportunities and recognition if you have the right manager. During an interview, make sure you 'select' a manager you can respect and who is well respected, you click with, and you are golden.
Cons
The other extreme - if you have an insensitive manager who doesn't get-it or care, it can be the worst place to work. That by itself is not unique to Lam. What one needs to be aware of is that it is very hit or miss with managers/leaders here. You can get extremely amazing ones that lead and inspire, and extremely horrible ones that berate, micromanage, and are totally out for themselves. Fortunately most key sr leadership positions are great. The competence is generally high but expect your experience to be very hit or miss.
