Avantages
Great benefits, good environment. You have freedom to grow and learn new things. The culture is great and positive most of the times, and you can default to trust with most colleagues. There are always new challenges to face and learn from. Most people are gamers and it's accepted to play during office hours as a break.
Inconvénients
Everything looks great for the first few months, but soon afterwards the hidden issues come to the surface. Compensation is lacking, as Dublin is super expensive. Hiring is really slow, many departments are constantly understaffed, making people overworked or having too much on their plate. Additionally there are a few lazy people that do the bare minimum, dragging their teams and others behind. Office politics are very real, despite a claim for meritocracy. There's a general 'we're awesome' mentality, but it's pretty superficial. There's a lot of things that need to improve.
