My issue is about the shotgun approach of many recruiters. I don't mind taking a coding test, I think they're great. It's frustrating to have to take a coding test to find out the area of the company, or pay grade, or basic position info. Or being put into a phone screening for a Java position because the recruiter mixed up Java and JavaScript, etc. etc.
This gets worse with the higher level of effort test. I think that it helps when companies describe the position well. Otherwise it takes some sort of knowledge of each other before I think it's worth actually dedicating time.
It may be different if you're looking for a job full time while unemployed. But spending 10 hours of time is only something I'll consider if I think I'd take the position should the org want to hire me.
This lack of respect of or recognition of the value of applicants time will filter out what’s likely your most desired applicants, people with low amounts of time due to current employment or lots of leads.
There needs to be some interaction with the applicant to show you are worthy of a mini project or multi-hour hackerrank test. Your job description better be amazing with details to motivate an applicant to spend time on a test off the bat.
