I've been trying to relocate into a different country (my partner lives there), but until now I've been unsuccessful. Currently I have been employed for three years, but my work history before was bad (2 year gap) and I assume this is a big factor as to why many of my applications remain unanswered.
My current job and job offer I refused were both offered after I've got their attention by impressing them with my solution. A lot of people criticize such a request for a variety of reasons, I do however like them. I can show them (at least as far as that's possible with coding challenges) my dedication, skills, problem solving and creative thinking.
I've beginning to think if I should include a sentence in which I offer doing such a coding challenge directly in my cover letter. Would this be a useful plan in my job search?
