Please stop the coding challenges

I recently ran an interview process for a relatively senior eng role at a tiny startup. Because I believe different interview methods work better for different people, I offered everyone a choice:

1. Do a takehome test, targeted to take about 4 hours but with no actual time limit. This was a non-algorithmic project that was just a stripped-down version of what I'd spent the last month on in actual work.

2. Do an onsite pairing exercise in 2 hours. This would be a version of #1, but more of "see how far we get in 2 hours."

3. Submit a code sample of pre-existing work.

Based on the ire I've seen takehome tests get, I figured we'd get a good spread between all three, but amazingly, ~90-95% of candidates chose the takehome test. That matches my preference as a candidate as well.

I don't know if this generalizes beyond this company/role, but it was an interesting datapoint - I was very surprised to find that most people preferred it!

Why would you even do any of that for a senior role? I wouldn't waste my time with it, and it shows you don't know how to interview/evaluate for a senior position.

Because for a senior role you need to hire a person with senior role skills, I suppose. Just N years of experience at X company doesn't provide that. I'd rather look at someone's github repo than talk to their reference tbh.

I've never worked at a company with a public repo. I never understood this. I have a life outside of work

Neither did I. But I'd rather just "smuggle" out some past work and "rewrite it" to make it inconspicuous, if I didn't have my own personal work to show. The company I work for isn't well known so saying "I worked there in a senior role for 10 years" isn't going to get me the next job. If I didn't have anything to show for that I either made for fun or could display from a past job, I'd not apply for another until I had tbh.

People say "No I don't have any past hobby work, never contributed to OSS, and all my professional work is verboten to show" that's not unusual, but it's also not an encouraging sign to me when interviewing.

Wouldn't that be a red flag if they don't have any public code at all as a senior developer? They aren't fresh out of school or just starting their careers. They should have something.
