> I'm hoping ABC's recruitment policy is flexible enough to let me offer alternative, or at least parallel, routes to quantifying my skill in coding [...] Would ABC be willing to work with me to define a better way to check my technical qualifications by choosing one of these projects?

It's good to see someone take the initiative to express this, but IMHO, it would be even better to just take the initiative to contribute to one of the proposed open source projects and put it on your resume, and participate in the Hackerrank part of the interview.

I like the proposals, and I'd probably land on the side of impressed if a candidate I was interested in sent me a letter like this. But, I still need a quick way to screen people, and I also need a set of standard questions that all candidates get so I can compare & rank them. I don't use Hackerrank, but I do ask easy weeder questions in the same style.

Then, after the candidate passes the easy part, I look at their portfolio of work projects and side projects, and consider everything they have to offer.
