Pros
Great people (in the UK) Good location and office Free fruit
Cons
A classic example of a successful, functioning company being purchased and put on the path to destruction by the new owners, who completely fail to understand it (and make no effort to do so) - especially in the area of technology. Sales targets are now all that matters, together with an irrational desire to combine products with those in the US (also purchased) that really don't sit together well. Since all senior managers report to staff in the US (and increasingly responsibilities are being shipped over there, impacting morale), many significant UK issues never get addressed, and the top-level management structure comes across as a 'dysfunctional family'. The general belief is that the end game is for the US company to take over the intellectual property and customers, and let the UK office wither.
