We felt it was important to have some kind of presence at the event because Rolls Royce is one of the larger UK arms companies, supplying weapons to a number of countries including parts for the Hawk jets which were sold to Indonesia. They also make parts for the UK's Weapons of Mass Destruction (Trident submarines).
We went into the recruitment event, which took the form of a presentation by a few Rolls Royce workers. We had some hastily-made leaflets with some info about the company to hand out to students attending the event to make sure they knew why we were there. Then we just sat down among the audience and asked questions at relevent bits during the presentation.

It went well in that we raised some issues that would not otherwise have been mentioned (for example the effects of the aerospace industry on climate change, the profits they make out of war, Rolls Royce's role in the terrorisation of people in East Timor). The company representative in charge of the presentation had the attitude that 'we're not here to discuss politics' and 'if I thought the company was that bad I wouldn't be in this job would I?' Some of the potential new recruits were interested in why we were there, but quite a lot seemed to already be aware of Rolls Royce's dodgy dealings and not be very concerned.

There is a timetable on the company website of recruitment talks they are giving at universities around the country - worth a look.
