Earlier quoted context omitted.
often you won't get hired if you've had more then 8-10 months of unemployment without reasonable explanation. I do a lot of hiring. You are correct and further - literally any gap at all is viewed as suspicious. And there aren't many reasonable explanations that help the situation.
So... "I gathered savings and wanted to rest for half a year" is suspicious? Maybe I am misunderstanding here.
I once, as an intern, had an HR assistant bring my application for a permanent position back to me because she wanted an explanation for why I was unemployed between June and August of the previous year (a year in which I was enrolled at a university.) I explained that I was in school and most companies don't hire people for only 3 months over the summer so I spent that time learning a programming language. She walked away looking annoyed.
