They're not a place I would consider. Former employer had some trouble, went out of business, technology was bought by GD. My contact was super burnt out after the closure, so he took a month and went to his folk's cabin in the woods to decompress, completely off the grid. Got back, GD was blowing up his phone wanting him to come there and work for them because the technology they bought was locked up in this guy's head. He said the recruiter left progressively angrier messages, and when he finally answered the recruiter's calls, recruiter was pretty pissy with him. He said the recruiter angrily told him that this was an opportunity not to miss and that if he came there he'd retire from the place, that's how long they kept people. Recruiter was apparently a super ass, and my contact told him to take a hike. Contact later told me that a few people GD did manage to hire were let go within 6 months, as soon as GD got the information they needed.
