Avantages
None. Unless you like to be part of vicious, bloody, dog fight everyday of your existence. The work equates to a ton of massive manual, boring and ops heavy work. The vesting schedule is terrible and deliberately weighted towards your 3 and 4th year with the company knowing all to well you most likely won't make it pass your second year. If you do make it past your second year be prepared to have a host of stress related maladies.
Inconvénients
There must be 10 male employees to every 1 female. The stack and yank method leads to backstabbing and petty politics that distract from getting quality work done. If you end up with a new manager, which you will, because this company is always re-organizing kiss your opportunities good by. Wages remain pretty stagnant after the two year bonuses fade and you can expect less that a 2 percent raise, even with an outstanding review.
