I stopped asking about "culture" and started asking why the last guy failed - it is the ultimate red flag detector

I am completely done with the generic interview advice that tells you to ask about growth opportunities or company culture. It is all garbage because managers just read from a script they got from HR. Last month I started a new tactic because I was sick of getting hired into roles that turned out to be total dumpster fires two weeks in. When they get to the part where they ask if I have questions I just look them in the eye and ask why the last guy in this role failed or what his biggest mistake was. The way they react tells you everything you need to know about the manger in about thirty seconds.

I had an interview for a senior dev role last week and when I asked this the hiring manger actually looked offended. He started rambling about how the previous guy lacked ownership and wasnt willing to jump on calls during his personal time when things broke. That is literally all I needed to hear. If I had asked about work-life balance he would have told me some lie about how they respect boundaries. By asking about the failure I forced him to admit that he expects you to be a slave to the pager 24/7. It saved me from a miserable six months and a quick quit.

Another time I asked it and the guy told me the last person was too focused on perfection and couldnt handle the pace. In dev talk that usually means they ship broken code and have zero testing protocols because everything is always on fire. It is such an easy way to see if you are walking into a toxic mess or a legitimate team. The best mangers actually get excited when you ask this. I had one dude give me a full post-mortem on a technical screw up and explained how they changed their CI/CD pipeline to stop it from happening again. That is a massive green flag. It shows they actually fix problems instead of just pointing fingers.

The best part is the awkward silence right after you ask it . You can see them trying to find a professional way to say the last guy was a human being who didnt want to be abused. It is way more useful than pretending to care about their inclusive environment or whatever other buzzwords they have on their website. I have already dodged three bullets using this question and I am going to keep using it until I find a boss who isnt a total clown.

Anyway I have another interview tomorrow and I am honestly just looking forward to seeing the hiring manager scramble for an answer.
