I applied online. A recruiter reached out 2 weeks later. I had a phone interview a week later with a Project Manager. He was very ambiguous with the role, and didn't want to specify whether he was interviewing me for a product design or PM role. It seemed like a positive interview experience overall, and I managed to answer the brain teaser correctly after a second try. However after that call, I was not invited to continue in the process.

Everyone was friendly in the interview process, however, it was a long process from start to finish. Initial interview with a recruiter, then a phone interview with hiring manager. After that, they will offer an in person interview typically.
