HR is pathetic and doesn't care about your valuable time.
HR didn't involve initially and asked the project manager to schedule interviews.
After clearing 3 technical interviews HR didn't call and the manager emailed to follow up with HR. Upon follow up there is no response.
When I updated the manager back, he followed up with HR, and finally, HR called, asked for my docs, and then again she ghosted me.
When I followed up again with the manager he said HR is not listening to us but I think they will soon going to release your offer, but they didn't.
DXC wasted 1 month of my time in the entire process and then just ghosted.
