Pros
In 2014, Sizmek (formerly Mediamind) really managed to turn around their culture following the departure from DG. Now have a strong set of global values and the company is very globally connected. Progression is available. There is always plenty of work to do when competing with Doubleclick/Google. Some very talented people work there who are loyal to the company that used to be Eyeblaster years ago. With over 44 offices worldwide it still feels like a small company and its easy to get things done and make decisions. Very flexible in terms of remote working policy and attire. Local offices are always in high spirits and greet travelers with open arms making it fun to travel.
Cons
Needs better support around initial training. Having such a global company can be a challenge, especially when so many developers are based in Israel. Need to have a thick skin for occasional client gripes and master clear communication with teams overseas.
