I'm glad I never had to go through such ridiculous hoops to get a job.
If I had I might have been inclined to say "Yes I could but I wouldn't do it because it would be unmaintainable."
Real application programming isn't about being concise it's about being cost effective. Sometimes conciseness achieves that end often it does not. Having a well named intermediate variable can help document what is happening so that the poor sod who has to fix a bug in or extend your code two years later doesn't have to spend an hour deciphering your code to apply a two minute fix. That poor sod might be the very same person who wrote it.
I liked Go and used to work on it in my personal time. Go's way of doing things is usually one way so there are not many things you have to remember about language. I applied for a job of Go and I landed that one. Of course, at that time very few Go developers were there in market so that could be a good reason for me landing that job as well.
