Discussed my background, a project that I worked on with the hiring manager. Next round spoke with a software engineer on the team. I was moved to the next round to do a take home to build a scheduling api. I was asked to do it in 3 days if possible. I submitted it and quickly rejected based on my product engineering background lacking platform engineering. I would assume that my background was sufficient before moving me to the round to speak with a software engineer and take home. My time was wasted. I'm sure my take home was not looked at, as I could not get feedback.
