This is cool, although I would hate to put 20 hours into solving this just to learn all the positions have been filled, or do a 15 minute interview with the company just for them to say I'm not a "culture" fit.<p>Neuralink sent me home with a 10 hour assignment writing 1000 lines of (reasonably math-heavy) code and they never even reviewed it. The HR lady kept saying the team was busy (reviewing other coding assignments), and after two weeks of pestering her she said they decided I didn't have enough experience. I know I probably sound salty (I am), but the code itself was impeccable.
As tempting as it is on the surface, it would require one stay / move to the USA. Given the current direction that country is taking that seems like an overall poor career move. As it stands you literally could not pay me to join the USA.
So you spend hours of your own time on a "challenge" to solve work problems, "4. Help solve Unsloth issues!", for their company, to potentially get a job offer?<p>And they get your work for free? What a scam.<p>This is worse than an unpaid internship, because at least you can put that on your resume.
