| Now take that list, throw it in the rubbish bin and wash your hands thoroughly. Take home challenges are simply an absurd waste of time and a huge disrespect towards your candidates personal time. You ask them to spend 4 or more hour of their free time on a useless, throwaway excersise that you "review" in 5 minutes and you conclude they're good enough because they laid out code the way you like it... You never see the really important things that you should be screening for: how they explain their approach, their though process, how well they communicate, the compromises they had to make to fit within the timeframe, and why they'd made those compromises, how they react and adapt to changing requirements and feedback... It's just flawed on so many levels... As a new Engineering Manager I've eliminated the take home challenge in my new company in favour of this process: - You have open source code or closed code that you can show? Walk me through it. Our best engineers passed the interview this way. - You don't have code to show, 1 hour live coding challenge, focus on communication, search want you want online, ask us any questions, and explain what you're doing. We had about 40 such interviewes this year, one person refused the live challenge, 11 passed this stage, and we ended up with 7 hires accepting the offer.

So now you've put candidates through a silly "live coding challenge" – offering an advantage to the sort of person who is chatty and communicative with strangers in a stressful environment and the expense of people who may be better engineers but slower to warm up.
I really wish folks would be way less dogmatic about this stuff. Every single time I see someone say "take-home exercises are bad", their proposed alternative is also critically flawed.
