That’s why you need unbiased information from someone you can trust, who doesn’t just know the jobs market, but knows the country too.

A “coding challenge” is a gamified bite-sized online problem-solving competition. It shows a software engineer’s technical skills; her/his approach to problem-solving; their ability to understand requirements and think clearly under pressure.
