DXC shouldn't make a difference. Few recruiters I've spoken to knew who DXC was. Although one said "I've heard of them, what do they do?"
Recruiters often expect a CV to show a trail of 3-5 yrs jobs so they see a kind of advancement trail. If you've been at once place for 10 years, they might ask "Why have to stayed there for so long?" I assume because they think you might be too used to doing things one way and may struggle with fitting in with new cultures. As their payment can be delayed up to 6 months whereby they only get 20% if you leave after 2 months and 100% if you complete 6 months.
You can make tell them how you had so many new client opportunities (at DXC) that you had no reason to leave, but as they continue to downsize and continue their move towards low-cost countries, that the opportunities open to you have diminished and so you are now ready to look for new challenges elsewhere, where you can lend your experience to helping other businesses....or some such stuff and be honest about the work you are looking for, but don't limit your scope too much.
