Firmenich Process Engineer interview questions

Was first contacted by Talent Aquisition about the position after applying through LinkedIn. It was a basic screening. Several weeks later, I was interviewed by HR and set up a technical interview. We had a two hour interview that I thought went well. They even said it went well in a follow up email. I didn't hear anything for over a month. I, politely, emailed several times to see what the status was with no immediate response. After I'd moved on with other opportunities, they'd finally sent an email rejection.
