Pros
I've been in high tech for a couple decades and I've worked for and with many of the most well known tech companies in the USA. LPL has the most mature technology process I have experienced and, while this could be a bad thing if it is ponderous the LPL implementation is well balanced between value vs effort. And the very best thing is that the company is expanding at such a pace that growth opportunities are endless. It is my observation that applying yourself at LPL will lead to a lucrative and interesting career.
Cons
While not exclusive to LPL rapid growth comes with growing pains. These manifest in political rivalries and long hours and I see that at the VP+ level at LPL. I have seen the same thing at other fast growing companies.
