Ex CSC here. I started in the Chesterfield office because they were local to me, hiring apprentices and I wanted a foot in the door. Quickly disabused of any silly notions I had of career opportunities given my first year was spent dumped on service desk and then backfilling roles lost to redundancy. I never got a significant pay rise past my initial apprentice salary and made the mistake of sticking around far too long before jumping somewhere that paid and treated me better.
That was a common strategy, promise apprentices the world, then dump them on the service desk. A common issue because they'd train apprentices and then lose them meaning they had a higher turnover rate than regulars. A lot of people weren't happy seeing apprentices taking the places of seasoned colleagues and having to train their replacements effectivelym
Some of the apprentices worked their backsides off and didnt deserve this flak. Some didn't and either washed out or faded into the background. Some took time to get into good habits like me, and I will be happy about it. Of the lot I knew only one still works at DXC and only because he was in a unique position that suited him.
A lot of the others who worked there were ex Royal Mail Group that stuck around waiting for VR and/or had good T&Cs from those days that made it worth then sticking around.
Funny enough, a lot of those veteran guys went on to form the backbone of places like ATOS, Littlefish and Capgemini.
