Pros
The QA Consulting office has an extremely nice vibe with loads of great people. Friday ends with drinks at the office and frequent gatherings at the local pub encourage you to get to know your co-workers and wind down after a stressful day. There is a pool table so break times are always exciting (Just make sure you pot at least one ball or you will end up on the 7-ball wall). There is also a sandwich delivery cart which brings fresh sandwiches and other goodies to the office every day. Once a year there is a QA Consulting 'conference' which is really just an excuse to fly all the 1+ year employees out somewhere hot (i.e...: Palma, Barcelona, ...) and have a big party!
Cons
When the office is full the internet can be a bit slow, and with the 12 weeks training every month people leave the office to go onsite so you'll be saying farewell to lots of friends (although if the're cool you'll see them one of the many meet-up events run by the marketing department)
