I worked at a sub-company within it, called Go Advertising.
It was a great place to work at - more so in the beginning. I was given a paid internship which was wonderful, and worked my way significantly higher up in a short space of time.
Unfortunately the Managing Director at the time was a bit of a problem, and I ended up being made to lease due to a conflict of interest. But everyone and everything else was great.
Wonderful people, lots of events and benefits, as well as a free bar!
Slightly corrupt managing director
