They only hire contractors / there is no path to actual employment. There do no offer benefits. You are completely isolated from all your colleagues/they do not facilitate any social activities or interactions. You won't have any friends at work and no one cares about you as a person. The pay is really really bad / not market standard.
They are only able to convince very subpar exercise physiologists to actually stay at the job, the good ones find out real quick it is not a place where you are valued or can grow. There are zero opportunities for growth.. they are basically just trying to keep the lights on. I had way too many concerns about patient safety during my short stint at this place.
Just don't do it.
