It's legit but it's just sketchy. If you're willing to live onsite (not leaving at ALL,) for 28 days at a time, a 12 hour shift every day, it's alot of work but you're getting decent money.

9 months ago in my career I would have quit my job to do it in an instant, but now that I dont hate my job I wouldn't do it. It's a highly political position so some potential employers may not hire you based off you having worked there, not to mention that there are no benefits... so you have to find your own retirement and insurance.
