Not great, but my experience is unusual
Pros
The people are generally kind and easy to work with, and for someone with little experience at the front desk, the volume of calls and scheduling and paperwork is really not awful.
Cons
Communication is abysmal. I was hired as a tutor, but when the former EC left, I took over on an interim basis, with the understanding that I would become permanent. Later on, they interviewed, trained, and hired a replacement without telling me, leaving me to fill in sporadically at other centers over December and January. Finally, the other former EC went on medical leave and never came back, so I continued working hoping my position might become permanent, but now with coronavirus, I have been left essentially without a position, and it was like pulling teeth to know where I actually stood.
