Took 8 weeks without feedback before a zoom interview. Asked about my education and when he reached an area I hadn't learned yet he asked me to intuit the rest.
There were 6 rounds of interviews asking questions from different aspects. Some focused on project experience, some focused on basic analog circuit questions. The interviews were arranged in one day.
