I applied through a staffing agency. The process took 2 months. I interviewed at Hart InterCivic (Austin, TX) in Oct 2020
Interview
Submit technical summaries (to the recruiter)
Several online interviews over some weeks with key people
Whole day onsite interview in their office and at partner's factory
Overall very friendly questions, and no mean questions.
Interview questions [1]
Question 1
There were certainly good amount of technical questions, but I felt they put more effort to make sure chemistry works well.
