This phenomenon will backfire on the company, long term.
I've had plenty of situations where I, the subject matter expert, had to step in where ill-experienced graduates or young professionals had created really nasty escalations with clients that could have reached the regional leadership teams.
Please note, I am not directing the blame to the graduates or young professionals; I've seen them trying their best to their knowledge and experience. My point is that DXC's management is placing these graduates and young professionals on clients or projects with critical impact, and in unfamiliar sectors with no professional supervision, just to save a few bucks. Something that they are no way ready for. This type of approach can get people ki---d if things go wrong depending on the business sector, such as health care or infrastructure.
Clients are becoming aware of this. What their answer will be? I think most of you already know the answer.
