I had an initial phone screen with Chief People Officer, where we chatted about my resume, background, skills, interest in the position, etc. A couple weeks later, I was invited to come into the Headquarters office (located in Lincoln Park) for a morning of in-person interviews with the CPO, CFO, CEO and Director of Design where we discussed the position in full.
I kept in contact with the team via email. I was given a job offer (via phone) a few weeks later, and then started two weeks after that.
