Avantages
You may find yourself lucky and find a team that actually works together. You may need a job NOW, then please apply here, it's just slightly better than the queue at the job centre
Inconvénients
Office facilities are horrendous - new office with temperature issues - so you could be in the Bahamas or in Arctic. Management in UK and parts of USA are fond of micro-management, so you are constantly wary of actually forgetting to tell them you have completed a task. There is a lot of backstabbing in this organisation, which i have not found anywhere else during my many years of employment elsewhere, you cannot trust the feedback you are given by management because it is all dependent upon their mood of the day. You don't get paid bonuses on time or properly. There is a lot of talk about loyalty, but there is no such thing.
