Pros
The only pros about Equinox is their clubs are gorgeous! However beware, as an employee there are so many restrictions that you can almost never use them unless you have a job where you can actually work out in the middle of the day. Since Equinox doesn't hire enough people per department this was practically an impossibility for me.
Cons
NO work life balance. You don't even get federal holidays off. The training and on-boarding experience is terrible. There was little to none in my department. Turnover is higher than I have ever seen at a corporate level and either Equinox is aware of the root of the problem and doesn't care or plans to continue the revolving door. I have never worked for a worse company. Unless you are desperate for a job my advice it to stay away.
