Pros
I have been In this company for longer that many others, the experience has been amazing, yes, working a lot but for good reasons. Here you have the chance of touching and playing with a lot of amazing technologies, the chance of traveling around the globe and considering GFI as a start up is not something to get as given. Being in a very tight environment you will have the chance of growing very fast and to learn at an incredible speed. Thomas Martensson is the CEO of the company, co-founder and former leader of this enterprise, he made this possible, surrounding him self of great people and expiring the team with his drive. He is not an easy person but stick around as long as possible and you will check out with a bag of knowledge that will be inestimable.
Cons
If you are looking for a place where to relax get your salary and work 9 to 5, keep on looking because this is not your place! Company like this, not necessarily start-ups, are for people that want to dedicate at least a part of their life to grow a quick great career and learn a lot. Sacrifices are hard but always reworded.
