ArgonDigital Product Manager interview questions

Started with a take home exercise that took several hours, a couple trick questions. Then an experience/behavioral interview with a surprise brain teaser. Then there was the ridiculous round where I was solely informed it was 'another brain teaser round you can't prepare for' where you are given a scenario about the stock market and you're supposed to give stock advice. I don't think this problem was solvable without prior stock market knowledge. I am not a stock advisor, I work in software. This is not Google, this is a 20 person consulting agency. I was ghosted at this stage without feedback. I asked several of my colleagues the same question and they came up with the same answer as me, so really don't know what they were looking for here. Came up with best and worst case scenarios, and asked all the boundary defining clarifying questions. Theoretically there was ANOTHER round after this dealing with a case study presentation. Seemed excessive after the take home exercise. This job market has made companies too bold. Overall way too many gotchas. I think they get off making themselves feel superior to other people.
