I'v been out of DXC for three years now, and a work colleague recently resigned from where I work now to go pursue his more specialized ambitions elsewhere.
I didn't feel jealous. I didn't feel envious. I didn't have a longing in my heart wishing that were me. I felt happy for him. For the first time in more years that I can count, happiness was the only emotion I felt at his news.
The emotional trauma of being at DXC is real, and the trauma will last for years afterwards. It's not worth it to your wellbeing to be there.
