Applied online and received a call from HR. Set up the formal interview and came in 30 mins early, and received a basic lab math test. Not sure why this is given to professionals with certified degrees, but overall not difficult. Waited for over an hour past interview time to be seen by HR. Interview was with HR and then with plant manager, and then HR. HR made it a point to highlight any work performed during the process of receiving a degree as a moot point and irrelevant in the professional sector..
