Pros
Opportunities (if one of few to get an interview) to get placed with blue-chip companies. Take on varying backgrounds and don't discriminate based on this/ take on those with a 2:2 Opportunity to develop skills that can help you in the workplace (presentation/confidence/IT skills)
Cons
Employees unable to communicate their concerns to newcomers as they get into trouble/damages the company's reputation. Persuaded by recruiters to join and made to seem better than it is Tied by strict contract - unpaid training period for about 2 months and it's sold that you get placed by the end of your training however this has not been the case for a lot of people. You then have to stay with them for another 90 days (still unpaid) while they try to find a place for you. Requirement to be geographically flexible and most likely move down to London (could be a pro if you want this). No support if circumstances change and you no longer want this/can't move which can cause a lot of stress/anxiety. Bad treatment of employees - opinion shared by most people i know that work there, seen more as an object with no freedom/space to choose not to relocate etc even if your circumstances change. You're expected to continue to be proactive and motivated even if you've finished your training, not being paid and might be forced to move to London outside of your will. Pay not great in comparison to similar roles if applying directly as company takes a very large cut.
