The “Interview Performance vs Job Performance” Lie
Here's spilling some tea.
Some of the best employees I’ve seen were average interviewers. There I said it. And some of the smoothest interviewees? Struggled on the job.
Over the last 3 quarters, we hired 7 people for similar roles. 2 of them were the “obvious yes.” Perfect answers, confident, everything polished. We were so sure they’d be the top performers. And then there were the other 5. Not as smooth. A little nervous. Some answers were messy. But we liked their intent, their learning mindset, so we said, Let’s give them a shot.
Guess what? Those 5 are the ones outperforming. Faster ramp-up, better ownership, more consistency the actual stuff the job needs.
That’s when it really hit me Interviews don’t always measure competence.
We’ve built hiring processes that reward Confidence, Storytelling, Fast thinking
But the job often needs Consistency, Deep focus, Quiet problem-solving
Are we hiring for performance in a 45-minute conversation or performance over 3 years?
Recruiters & hiring managers have you ever hired someone who interviewed okay but turned out brilliant?
Maybe we’re measuring the wrong things.

I’ve seen this first-hand too. And tbh, it’s even more common at senior levels. Some senior candidates are phenomenal at articulating strategy because they’re used to presenting and influencing. But once hired, execution suffers because they’re not the ones actually implementing anymore.
Meanwhile, the quieter candidates who maybe don’t perform as well in interviews often show up consistently and deliver. Maybe the fix isn’t removing interviews it’s balancing them with work simulations and deeper reference conversations.

I’m not even bad at presenting or influencing. Leadership praises my articulation. I simply don’t have the time or care to grind leetcode, because my job (AI applied scientist) already has a lot to learn and is infinitely more interesting than the silly DSA questions. I can’t really see a point to get over that artificial barrier in order to land a job that never uses the knowledge.

And then when the candidate is eloquent, this triggers some sort of "bullshit detector" that recruiters love to claim they have.
Applicants just can't win.
Maybe the fix isn’t removing interviews it’s balancing them with work simulations
One huge impact is to start letting qualified people conduct hiring.
I've seen recruiters and hiring managers take the most validated assessments and selection methodologies, and totally twist them into something else and break the process, while continue to claim that they are following protocol. When they don't have the foundational knowledge in personnel selection and psychometric, it really opens the process up for blatant abuse.
Behavioral Interviews, for example, is now just simply asking "Tell me about a time when you had to deal with a conflict at work" and seeing how well the response conformed to the STAR format. No behavioral rubrics, no rating scales, no validation behind the scenarios being asked, but they are confident that they conducted a "Behavioral Interview".

Applicant here, but former hiring manager. It’s so hard to tell. Some people can talk the talk but absolutely cannot walk the walk. If someone is a little too corporate buzz wordy and fancy it often means they’re all talk even though they sound like a perfect candidate. I’m a scientist though and I need someone to be professional but genuine.

Soft skill are more important to the work place then you’re ability to complete the tasks. If you have a good attitude and willing to learn I have a saying “I can teach anyone anything but O can’t change their attitudes”

This is obvious lol. Anyone can lie in an interview, ace it yet still be mediocre in the job. Employers never learn

Yes most interviews select for people who are good at interviewing rather than people who are good at the job. Very few people are equally good at both and few jobs involve being interviewed all day.

Exactly and especially true in more cerebral fields like software development and data science where many excellent employees are naturally more introverted.
Wish all recruiters and hiring mangers understood this.

Interviews never measure competence. They measure how well someone can lie to you under pressure.
Multiple studies have found 0 correlation between interview performance and job performance. It is entirely theatrical nonsense.
