Pros
The company has changed in the last two years with a a new CEO and management team. The people you work with day to day and the clients are what make the job fun. Develop good relationships with the clients and you can enjoy your time here. However, this may not be reason enough if you are looking for a career.
Cons
The new CEO has appointed a number of senior management roles and a lot of these are filled with people who have no idea what they are doing. There are also countless levels of management and reporting lines so that there is no direct route to Senior management anymore and they have become anonymous. A number of the Datasite sales team (the companies core business) have been with the company for some time and there is a level of arrogance and self interest with the senior Datasite team that precludes anyone joining from getting on quickly. Be wary as they cannot be trusted and will happily steal business from you and take credit and commission for your work if you let them. This is not a pleasant company to work for for these reasons and I would not recommend it unless you just need a stopgap while you look for something better.
