So as an ex apprentice who left last year I warn any other would-be apprentices / grads to use DXC as a stepping stone to better things and expect nothing more.
I was on less than £20k a year and despite being promised a pay rise to £30k+ for the role I moved into (which came with a promotion to Level 4) I still wasn’t any better a year later.
All answers I got were "the DXC process makes it difficult to get a pay rise of more than 10%" and "X manager is very process driven" but they were happy to bring in new staff to my team at £40-50k a year (like the 3 "proactive problem managers" brought into aerospace for a total of £160k)
Most of the people I know to be left are ex grads / apprentices & entry level people who got promoted into mid-senior roles without any of the managerial authority or financial benefits it should entail.
If you work on BAE, use it as an opportunity to gain some experience / credibility as they are a good example of the client hiring talent inhouse. I know quite a few ex DXC folks who got recruited by the client particularly in service management.
Don't hang around any longer than you need.
