Applied online. Got a phone call from HR just confirming I was still interested. Once she realized I was she set up a phone interview with a guy who was currently in their development program. The interview was behavioral questions that lasted about a hour. It was very enjoyable as we had a lot in common. Next, they flew me to HQ in Moline, IL where I had 2 1x1 interviews and a final post interview with the head HR lady where I got to ask questions. After we had the chance to go to HQ and have lunch with 2 people in the development program. They paid for everything. Overall, it was super enjoyable and couldn't have asked for a better experience.

Interview is a STAR interview process. It is typically multiple interviews with panels made up of peers. They ask questions and then you provide examples relating to the question asked.
