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.

Why wouldn’t you? How should one evaluate a senior position, in your opinion? Are you suggesting a senior dev shouldn’t need to demonstrate any coding skill? (If not, why not?) Or are you suggesting that there are other faster ways to show coding skills?

I responded to a different comment but it's also relevant here.

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.

You'd think so, but during the interviews I did, there are plenty of candidates to senior positions who just cannot code.

They talk the great talk about problem solving and team work and mentoring, but once it's time walk the walk, they just can't seem to write any code - and we are not talking advanced algorithms, we are talking Fizz-Buzz level.

Maybe it's different for doctors, but as long as such people exist and apply to jobs, we need to ask programming questions.

This also means that if _you_ are applying to a job in a larger team for a senior position and they did not ask you for any coding questions, they either:

- Really good for firing people fast for low performance

- Have people at "senior" position which just give advice and nasty code reviews, but don't actually write any code.

Either way, it's a red flag for the company.
