Pros
Almost a decade of my life - very proud of what I was doing and how Lam treated me - except for the last 8-10 months - when it became purely a confused state of affairs. Pay is way above average - not that it makes a difference when you work 60+ hours a week, but for the most part - 75% of the time I was with Lam - compensation was excellent, advancement was good - and my management, overall, was very supportive.
Cons
In the middle world of Lam - There is a general lack of communication - too much tribal knowledge, and several instances of cronyism. It's 50-50 - many technically sound personnel, but there is alot of fluff internally, in some cases sheer confusion by middle management (who don't truly understand the product or what the customer seeks), or lack of foresight (continuously repeating tests that have no conclusive data, which wastes time and money) and apparently some who think they are almost deities. In my last position - Management - didn't know (obviously did not understand) what I was doing and wasn't the least bit concerned that I was working 60+ hours per week trying to 'keep up' with the workload - having to carry the load for others who found it better to prove themselves as an asset by keeping close proximity to management's backside. Don't try to think outside the box and have it appreciated - and never tell anyone the truth, although that is one of the key principles that Lam impresses upon you to express, with respect, but it does have it's consequences (in this instance and with this particular manager, highly counter-productive to your continued employment). Clear communication and goal guidance (big picture) can be severely lacking. Also - for the field - SAP completely inhibits productivity. Nice place to make and keep records, but it is time consuming and inhibits supporting the overall productivity of the products sold by Lam.
