Fully technical with detailed projects, achievements & past experience. Chemistry & product knowledge must be understood prior to interview. Initially they have screened with tele-call & then face to face interview.

Met them at my schools Career Fair. They contacted me for a phone interview 5 months later. Phone interview was with a manager, no questions asked about my resume at all. It was a light ~30 min talk about the position, my goals etc. Was called for an onsite Interview with 4 other applicants. We took turns being interviewed by 2 managers (engineers), 1 chemist, 1 engineer, and HR. One manager put some tough questions forward. All other presented the standard interview and went over my resume.
