Avantor Associate Design Engineer interview questions

I applied online and then tried to schedule a phone screening but the HR rep was extremely difficult during the process. Every time I gave them very ample time slots I was free they kept trying to schedule interviews during times I said I wasn't. After that I had an onsite interview and the same scheduling issues persisted. Once I was there I had three rounds of interviews 1on1 and then a facility tour. The environment was very relaxed and everyone was super friendly.
