Pros
I started at Virtustream less than 2 years out of school as a financial analyst. I knew a lot about financial models and excel, but didn't know a thing about cloud computing or much else for that matter. The senior management at Virtustream took me under their wings, and taught me everything from the difference between SATA and SAS disc drives to how to raise capital to managing employees. Within my first few months at the firm, the CEO/CTO invited me over his house on a Saturday afternoon to spend an afternoon teaching me about cloud. Here I am, this young financial analyst with no knowledge of cloud computing getting a cloud 101 lesson from the CEO/CTO of the whole company. Management does a great job listening to their employees and helping them grow. After working at the firm for about a year, I told the Chairman/CEO that I wanted to have more customer facing experience. Next thing I knew he had me in a meeting with our largest customer at the time. What I have found at Virtustream is the more you put in the more you get out. I work very hard for Virtustream, and the Company works just as hard for me. If I were at a big company I would never get the senior management interface or responsibilities. At a small company I wouldn't have the opportunity to interface with Fortune 500 CFOs and top notch venture capital firms. Virtustream has the best of both worlds. We are young and fast enough to allow for fast personal growth, but have enough industry credibility and senior leadership to give you access to the best of the industry.
Cons
This is a venture growth firm, and with that don't expect the same things you would see at a 100,000 person firm. If you aren't willing to work hard and get your hands dirty, this probably isn't the right place for you. If you hate red tape and endless corporate policies, this is the firm for you, but if you don't like to get into the details then Virtustream may not be best for you.
