I hate these take-home code projects, to a point where I won't do them for similar reasons that you mentioned ("we're not moving forward, we will keep your resume on file!").

It's sort of a selfish way of interviewing; to write good code for these projects, it can take me upwards of 8 hours. An engineer where I live (NYC) can fairly easily make $50/hour (usually more), so they effectively expect me to give $350-450 of time for this company where there's a fairly high likelihood that they'll tell me to buzz off. I typically write in a very functional lispy style (even when I did JavaScript), and while the overall understanding of FP has improved in the last couple years, a lot of the interviewers would simply not understand what I was writing, and ask me to write it "more object oriented".

Big corporations like Google can get away with that, but for a small startup I really don't think it's worth it to do them (not to mention that I had a friend who did one of these assignments, and they ended up using his code in production without paying him).

The good data science take-home assignments I've done suggest a 2-3 hour limit and they were correctly scoped for that limit, although technically there's no incentive for the candidate to stick to that limit.

The worst take home I did suspiciously did not have an expected time limit (but was due in 48 hours after issuing). It was extremely broadly scoped, and as a result it took 16 hours; even after a couple years as a data scientist now and familiar with time-saving tricks, it would still take 8 hours minimum if you weren't already familiar with the company's data.

Even 2-3 hours is pretty high, expecting me to spend $100-150 of labor for it.

16 hours is kind of insane and you have my sympathies. My record is around 10 hours.

"I typically write in a very functional lispy style (even when I did JavaScript), and while the overall understanding of FP has improved in the last couple years, a lot of the interviewers would simply not understand what I was writing, and ask me to write it "more object oriented"."

Which is a good way for you to weed out companies where the developers are low to average intelligence.

Not understanding basic functional programming concepts, in 2019? Seriously?

In fairness, the times this happened was 2015, so about four years ago. Still, even by then it was getting to the "it's not ok to not know this" territory.
