I inquired PwC about the CEO, he indicated on LinkedIn that he worked there. They responded: "We have checked with our HC teams, and we have no record of somebody of that name working for PwC UK".
I think it's time to mark this project as 100% SCAM
Becareful with it and that means if this project was lying about that. There were so many scam projects lying about their identity. if that's the true story and this project has a very big probability to be the next scam project.
CEO was lying about his job and that means it could be a fake identity. This project must be putted into the suspicious project's list.
