The interview process consisted of a telephone interview with HR and then lead to a MS Teams interview with 2 Process Engineers. Overall very well done. I rejected the 2nd interview due to salary concerns.

First, there is a phone interview with an HR person. Then, there's a virtual interview with Hiring Manager and Director of Engineering for the site. That's as far as I got, but I believe there is a panel interview after that. The Hiring Manager was fine, but the Director was really rude. It felt like he made up in his mind that I was exaggerating my experience and started nitpicking every little detail. He was also pompous and went on and on about how he used work at [insert prestigious company] and conduct interviews there.
