Please stop the coding challenges

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!

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.

Through all of the technical interviews I've run on behalf of multiple companies, I've become convinced that our industry is full of imposters. A terrifying number of people who are employed as developers cannot code, beyond making tiny edits to existing code, or slinging StackOverflow answers and AI generated content around. They cannot think for themselves. They rely heavily on their coworkers to make any substantial progress. If anything, modern AIs have made these people more difficult to spot. I've found these imposters within the companies I've worked for too, and if it's not possible to move them to a non-technical role where they can be productive, then it's best to fire them. If that isn't possible, then keep them out of the way of any critical work, but know that they'll continue to be a drag on their team, and will decrease the moral of those on their team who have to keep covering for them.

Once I even worked on a team (as a junior) where only 3 members out of ~16 even knew the language that was exclusively used for the job. The remaining team members accomplished nothing every day. Those stand-up meetings were painful. Drawn out to 45+ minutes of standing in a circle while the unproductive team members found new ways to explain why they haven't made progress. Then I'd see them return to their desks, and not even open their IDEs for weeks at a time. They seemed to keep their jobs because their boss didn't want to fire them, and it cost him nothing personally to keep them around, offering them a sort of corporate welfare. Perhaps having such a large team even helped him politically, but it's unclear if he cared about that since he also spent almost all of his time slacking off, playing games in the break room, while the 3 productive team members carried the rest of the team.
