Process
Extremely disorganized, with a poor choice of technical questions and a silly coding homework exercise that they barely look at and take interest in.
Interviews ran into way more hiccups at all stages than excusable for a company of this size.
As others have noted, DO NOT waste your time with the silly homework assignment and a company that doesn't respect candidates' time.
Questions
Take-home project with very few relevant questions.
