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.

I've come around to the idea that all people who will be expected to write code as part of their job need to be evaluated for their ability to write code as part of the interview process. I've seen too many people write convincing and impressive resumes without a single ounce of technical ability to their name.

You're hiring for a senior role, not a junior or mid.

Your candidates aren't fresh out of school or just starting their careers. They already have plenty of work experience. They already know how to code and have been doing it for years. A conversation will tell you much more about their approaches to problems solving, team work, and mentoring than a coding challenge will. Looking at their GitHub, their work experience and references will tell you the rest.

It's like asking a doctor to go over basic human anatomy.
