Pluspunten
i4i has great culture and work environment. People are friendly and stay very close with each other, both at and off work, for both current and former employees. It can be especially good for people starting out their careers when they are learning to navigate the work life. The company sponsors work visa so there are many international employees. Good work-life balance, flexibility and generous PTO days. The senior leaders are some of the most experienced experts in the marketing research industry. You'd learn a lot from them. The company in general encourages creativity and welcomes good ideas. You'd have the opportunity to make an impact with your ideas if they are good.
Minpunten
Most cons you'd expect working for a small company: lack of management and structure, less potential for advancement, etc.
