Flexport Manager, Pricing Data Systems interview questions

Phone screen with HR. Phone screen with hiring manager. Hiring manager was about 15 minutes late to the call. Note that the briefing I was sent prior to this indicated that them being late to the call might be a test! A test of your willingness to be treated poorly by a company, it seems. I guess I passed, because I was given a homework assignment. Fine, but curiously, the instructions were to do the work in Excel. Now, this role ostensibly is to create a robust, scalable pricing data system. So why would someone's Excel skills come into play? Despite my gut feel that this is some ridiculous MBA Excel jockey garbage, I asked if I could do the work in Python, rather than Excel, which I thought would be a real plus. I did the work, but there was some missing data and some unclear instructions in one area, so I asked some clarifying questions. I received no response to my clarifying questions. They just ghosted me. If this review can prevent a great data engineering manager from wasting their time with Flexport, I'll have done my good deed for the day. TL;DR: Hiring manager 15 min late to a phone screen, homework better suited to Excel jockeys than data engineers, company ghosted me after I did their ridiculous assignment.
