Exactly this. Might I suggest the next time a company asks you to do a project, tell them you don't work for free. It's tough sometimes because you really want the job, but in my experience, every single time I've broken my "not working for free" rule, I ended up doing work for a job I never got. What I'm trying to say is that there's a correlation between bad companies and tests like these.

For a quick project I think you did a great job, BTW, though there should never be any need for sudo. That was the only decent feedback honestfeedback provided. The rest is BS.

Cool. If you wind up in southern California hit me up.
