Do a take-home project but don't make them write from scratch. Give them a mostly working starter application.
Sprinkle in some bugs. Start with easy spelling errors and go all the way to concurrency problems.
Ask them to add a few simple features and fix any bugs they find. Bonus points if they find bugs you didn't add intentionally. Good unit tests are also a bonus.
Give them a couple days or something. Don't count off if they don't get everything done. It's better to do a few things correctly that fix everything with hacks.
Invite them to email questions/suggestions to the hiring team. This person might be on your team so it's nice to find out early if they have good ideas or they hound you with stack overflow questions all day.
I've never had this kind of interview but it sounds nice to me. It's more realistic to real daily work. You can cheat by having someone else do the work but that's always a possibility.
This sounds sadistic to me. I've spent a long time on dumb typos, which become a lot harder to spot when you are stressed and on a deadline. Chances are if you are applying for work, you are probably stressed about not having a job.
You've completely missed my point. It's not about being perfect. I want to work with people who leave code better than they found it but I can't expect perfection. I don't care if they can't find all the typos. I'm sure most software has typos.
Whiteboardimg a solution to n=np or building full applications is crazy and not realistic. Most interviews do that yet most work is fixing bugs and adding mundane features. Why can't interviews focus on the actual skills needed?
