Pros
Great comradery, can potentially earn good money if you're allowed to progress.
Cons
Not enough holiday leave (20 days) for the hours that you put in. (contracted 50 hours / week - 8am-6pm, yes you do often work through lunch as there is no canteen so you eat at your desk and the phone will ring during your break!) If standard hours weren't long enough you are expected to work overtime - arriving 30 mins to 1 hour early and leave 30 mins to 1 hour late - especially in more junior positions. Management is poor, dependent on what team you work in. Sales managers have little responsibility but to 'drive the team' which means taking you out of office for 45mins-1hour a day to discuss/bollock you for not hitting KPI's and targets which are twice as high as competitors, meanwhile you fall further behind in meeting said KPI's and sales targets.
