I think the supervisors under whom you are working could make or break the job...
As a Chicagoland resident, you are familiar with Coldwell Banker real estate—They are ubiquitous! I worked at 2 CB branch offices. Same job description—absolutely loved one of the offices, the other not so much (at all!)
I would consider going to interview—you are interviewing them as much as they you. Hopefully they give you a tour, and you get to meet some of the supervisory staff as well as see the working conditions, some potential colleagues, etc.
From your post, sounds like you are interested in the health benefits offered by a large corporation. If that is important, a stable company would be important. Love them or hate them, I think Amazon in some form is here for the long haul, and if you like it, you could move up.
Good luck!
