I applied online. The process took 2 months. I interviewed at GAF (Indiana, PA) in Jun 2021
Interview
3 phone calls, 1 plant visit, plant visit included a panel and plant / lab tours. Interviews were behavior based with several follow up questions. All the people I interviewed with were very smart and very kind.
It was pretty straightforward. Spoke initially with a recruiter to learn more about the role, then progressed to meet with 3-4 team members back to back virtually. Was offered the role a few days later.
