Pros
I really like working here, everyone is really friendly, the work I do is meaningful and I'm recognised for things I do well, on the flip side when I'm struggling or unsure there is always someone there to help me. The people that work here are some of the most talented people I've ever met. I always think its a good thing when you feel like the idiot in the room. There are offices all over the UK so if you don't want to be based in London there are alternatives There are always social events going on, Beers in the local pub or sports and activities. I go and play football on a Wednesday lunch time and rugby on a Thursday. There is a good canteen providing Breakfast and lunch everyday.
Cons
The office needs to be updated - I think there are plans to do this soon though. other than that its just really good.
