It was a 20minute phone interview. They were all expected questions, and with my Ph.D. in consumer behavior and industry experience, I had all the qualifications they were looking for. I have no clue about why I could not make it to the next step, and I was not planning to ask. Anyways, in the email it was saying, they can not give feedback to candidates about their interviews.

Phone Screen with recruiter to discuss table stakes and logistics and some basic behavioral questions, 50 min meeting with hiring manager with more behavioral and technical questions, 30 min research presentation to team about recent project, five 45 minute virtual onsite interviews with team members
