Vantaggi
Everyone was a delight, didn't meet a single person there who I disliked or didn't want to work with. Weekly tea tasting sessions were loads of fun. No sense of management giving an impression that they're "better" than you are because of their position (everyone's in the same office no fancy floor or anything special just for execs), new ideas are respected and appreciated and just generally a really respectful place. You get to drink as much *delicious* tea as you like.
Svantaggi
Small company, so any career movement requires either an increase in size or for someone else to leave. Company arrangement means lots of different people need to test and approve things before they can be released/commenced (marketing/products/events) which seemed really inefficient to me, and means that things need to be planned way in advance.
