Submitted my resume and work samples through their online job application. Received an email from an Autodesk recruiter a month later.
The recruiter arranged a phone interview with me and was very accommodating to my schedule. We spent half an hour having a friendly conversation on the phone. We discussed the product and ways to improve it. She asked specific questions that clarified the role and experience level. I didn't do too well on these questions since I don't have much experience in product management.
By the end of our chat it was clear I was not qualified for the job, but she was still interested in my background and asked if she could forward my information to another department that was looking for someone with my background.
