My resume was submitted by an employee as a referral. They contacted me the next business day about scheduling a phone interview. It took a day to hear back from them wanting to move forward with my application, so I got scheduled for an on-site a few days after.

3 rounds, first is phone interview with basic introduction, second round is interview by junior, third round is a case interview with a supply chain scenario were you have to answer how you would deal with a problematic situation.
