Pros
Great teamwork and friendly atmosphere! Everyone is very open and positive, especially Management (which was a surprise!). My colleagues and CIO were supportive and helped me greatly not only with the daily tasks and overall projects, but with my personal professional growth, too - I learned a lot! Despite being a small company, it really put effort in growing and making everyone feel great and part of the team. It was the perfect place for me, because before that, as a uni student, I did some internships and full-time junior work for companies that never really acknowledged my work, or me as a person. At FSI I got the chance to work with many people on different projects, which made me feel confident enough to pursue full-time freelance work.
Cons
Back in my days, the company was in Piraeus near the harbor, which made commuting hard... It was also a place with heavy traffic and very polluted - almost unbearable in summer. I hear they moved to a better location. Also, sometimes deadlines were tight, since the international betting industry is a demanding sector. But there were always team perks and fun after a pressing, long-hours project - like pizza parties and time off!
