Instacart Senior Data Scientist interview questions

Very chill initially. Spoke with a recruiter from a third party company, he was great. Made the role out to be more of a data analyst/ETL dev role, which was fine. He passed me along to Instacart, and they liked my resume. Initially they give you a tricky SQL query. It was really easy once you understand what the question is asking (ambiguous wording was a problem here) - took about 5 min to write after 5 min of reading it over and over again. Then I chatted with a recruiter from Instacart; 10/10 most awkward conversation I've had. Lastly, I was given a coding challenge. They don't give you any direction for this - "find insights" and another question that was similarly open ended. I assumed it would be best to take a data analyst approach to the problem since that is how the role was described to me, so I did a lot of graphing and group bys. I spent a few hours on it (they tell you 4-6 hrs is typical). I think I probably could have used Tableau, but I didn't want to use my work computer, so I just did everything in Python. Heard back quickly that I did not get the role. I think the process was smooth, but given that I received 0 feedback on my assessment and the assessment covered about 40% of what I was told I would be doing in the role, I'm giving this a thumbs down. I think if someone spends numerous hours on an assignment, they should be some courteous enough to tell them where they can improve.
