Yep , didnt even answer, I had similar interviews solving company problems but that one takes the lead, I still keep the email, hope someone from their team will read so they can re-calibrate their view

They get crazy entitled during bear markets. It happened to me with Square in 2011, they wanted like an app to prove my skills just to get an interview. Like a full-on mobile app just to prove how hard I wanted the job.

Thing is, let it be known, every homework you do for a company lowers your salary by 3%. Unless you charge, then it doesn't, it's weird like picking up money off the street. Just bad signaling, it's against your interest.
