LeetCode and Let Die
Technical Interviews Reject the Wrong Engineers
Hiring tests are flunking great people, and the comments are absolutely not calm
TLDR: The article says common tech interviews often reject strong candidates for being bad at pressure-filled test performances, not bad at the job itself. Commenters were split between furious agreement, cynical shrugs that nobody has a better system, and calls for simpler, more human hiring.
Tech hiring just got dragged, and honestly, the comments are where the real bloodbath is. The article argues that many coding interviews don’t actually find the best engineers — they mostly reward people who practiced the right puzzle tricks, while rejecting experienced people who simply don’t perform well in a high-pressure spotlight. It also throws cold water on those scary “bad hire” stats floating around online, saying some of the most repeated numbers appear to be citation chain gossip rather than solid evidence. The bigger danger, the author says, isn’t missing a superstar — it’s accidentally hiring someone toxic who hurts the whole team.
That set off a familiar internet brawl. One camp basically screamed, “No kidding!” with commenter zipy124 saying good engineers won’t sit through a “12 step process” and that these marathon interviews mostly attract the desperate. Another crowd wanted solutions, not vibes: IshKebab bluntly said everyone already knows the process is bad and complained the author isn’t offering a better replacement. Meanwhile, a-dub pitched a much more human-sounding idea: skip the circus, tell candidates what matters, and let them explain how they’d actually help.
Then came the spicy contradiction. techblueberry called out what many see as hiring’s favorite hypocrisy: companies say communication matters, then complain when engineers can’t instantly explain every bit of “gut feel” knowledge under pressure. Others chimed in with a calmer reform vibe, saying simpler questions and better rubrics are working. Translation: everyone agrees the system is weird — they just can’t agree whether it’s broken, unavoidable, or both.
Key Points
- •The article argues that technical interview processes often reward rehearsed interview performance rather than real engineering ability.
- •It says widely cited hiring-cost statistics attributed to the U.S. Department of Labor and Harvard Business Review could not be traced to original sources.
- •The article cites a 2012 Center for American Progress review finding a median replacement cost of about 21% of annual salary, rising to 213% for senior roles.
- •It highlights a 2015 Harvard Business School study by Housman and Minor showing that avoiding toxic workers produced roughly twice the return of hiring star performers.
- •The article cites a 2020 study by Behroozi et al. suggesting observed whiteboard interview conditions significantly reduce candidate performance and may disproportionately affect women.
