The hiring manager (Sr Director) called me directly instead of HR. It was a little bit strange. The interview went really well, and she asked for my references, which was a bit strange, too. I sent her my references and a follow-up email to make sure she received them. She didn't respond to my email. After a week, I sent another follow-up email, but no response again, sent another follow up email after 2 weeks, again no response. A month later I received an email from Merck HR saying that I was not chosen for this role.
A company at Merck level should not act like that. They could be more professional.
