> Our biggest hit for a question that followed this for an SRE type role: we had a cron job that was legacy and buggy and caused a couple of issues over 6 months. We went back and created a very similar script with very similar bugs, added some similar data and re-seeding scripts, and told the candidates "customers say that feature $x is not working, and that is ran by this script. Here is how to run it, here is the user's id that can be found in the data seed." We added some other data validation problems. After they fixed it, we asked them what they would do to make this more production safe and dig in on what they have and have not done for improving existing systems. We expected discussions on structured logging, metrics, alerting, testing, code layout, etc. No wonder it is a hit. It is an actual problem that makes me want to go for it - I want to take an interview like this, instead of the usual of dreading interviews! Keep it up.
