Ventajas
You get to sit down. There's air conditioning. Parking was decent. The view from the office was nice.
Desventajas
Top to bottom dishonest practices. Management was downright cruel, and it seemed intentional to me. Extremely unprofessional. The work itself was difficult and you could expect to be yelled at over the phone. 100% turnover appeared to be the weekly norm. Every fair, negative review I've seen has been quickly and quietly removed, including my own. I was hired, including submitting all of the new hire paperwork, but was sent home to be "on reserve" or something to that effect. Once a handful of people had quit (about a day), they called me in. The new-hire who won the weekly iPad raffle actually called me after I had quit, as a hiring manager, because they had forgotten that I had worked there the week before. Disorganized. Beyond stressful.
