CyrusOne set me up to Fail. Here was my experience:

Pros

The 401(k) and health insurance options are decent. Although I did have to pay a $100 fee to Principal to rollover the $500 in my account upon my exit.

Cons

• I left a good job to join CyrusOne for what I believed would be an enthralling career. Turns out they’re very disorganized; trying to transition from start-up to mature company, but struggling with capital costs and political setbacks. • The HR and the talent acquisition teams are a mess. The interview process took 5 months. A background check was conducted by a 3rd party.. I will say this group was very unprofessional – rude to me and my references. Further reference checks and a drug test were performed. On my first day, security sent me home because HR hadn't communicated to them that I was starting. The invasiveness and sloppiness of this process should have convinced me to withdraw, but I was too nice and gave them the benefit of the doubt. • Poor corporate planning. The executives have MBAs from elite universities, but it seems they missed the classes on ethics and capital budgeting. Corporate has been exceeding its budget by 8 figure sums every month for the past year and their CFO likes to joke about firing employees. • It turns out the CFO doesn't joke.. I was laid off just weeks after joining as part of a “downsizing”. Imagine having to tell your family that the job you just started is no longer.. • On the inside corporate employees complain about a lack of career growth while data center technicians and facilities managers feel abused. It seems like there are 50 layers between the data hall floor and the C-Suite, and every level is pointing fingers at one another blaming each other. Corporate is extremely disconnected from what goes on in the data halls and there is high turnover. • When you start, they will force a very restrictive non-compete against you. Even if you are seeking employment as an entry-level technician, be warned. CyrusOne will come after you if you leave for a competitor. There is a famous incident of a recent service technician ($25/hr job) who left for a competitor -- they are SUING HIM. • The ownership, KKR/GIP, is coming to the end of its hold period. As such, they will be making significant cuts to improve their margins as they prepare to sell the company or take it public. Private equity looks shiny, but it is NOT worth it. • Some advice: Don’t relocate for this company and don’t sign the non-compete. Their CEO didn’t, so why should you?

Pros

Pleasant working environment, opportunities to collaborate across various areas of the business.

Cons

Communication to employees were siloed. Leadership seemed heavily focused on leaders and not on all employees.
