Century Support Services interview questions

1st round screening with HR, a few weeks later interviewed with the hiring manager, 95% matched with their requirements. And then another a few weeks later interviewed with a group of VPs. The whole process took about 3 months, all went well, and the HR said they would wrap it up in a week and promised to keep me updated no matter what. However never heard anything from them after that. Even if I sent a couple of emails to the HR and hiring team to ask for updates. They just keep ignoring. No updates, no rejection email. nothing. Wasting time.
