I applied through college or university. The process took 4 weeks. I interviewed at IMC Technologies (Urbana, IL) in Nov 2017
Interview
Do two online tests, basically testing IQ. Got an email of video invitation. Chatted with HR and talk about general questions about your background and motivation. Two simple option payoff questions. Then take the microphone and ask questions to HR about the company and positions. Generally, very easy.
