5 Common Hiring Mistakes and How to Avoid Them

Hiring the right person can transform your business.

‍

Hiring the wrong one? It’ll quietly bleed you of time, money, and momentum.

‍

Research shows a bad hire can cost upwards of $50,000 when you factor in lost productivity, time spent managing underperformance, and the cost of finding a replacement.

‍

But here’s the good news:

Most hiring mistakes aren’t bad luck - they’re preventable.

‍

If you want to avoid hiring mistakes before they cost you, you’re in the right place.

‍

Mistake #1: Judging Candidates Based on Their Resume First

‍

Most hiring managers start with the resume.

‍

That’s what everyone does, right?

‍

The problem? Resumes are loaded with unconscious bias.

‍

You see a name, a company, or a career gap—and your brain starts filling in the blanks.

‍

You’re not judging the person. You’re judging what the paper tells you about them.

‍

And once that impression is formed, it’s hard to undo.

‍

You might overlook a great candidate… or fast-track someone who interviews well but underdelivers.

‍

The Fix: Start With Screening Questions, Not CVs

‍

Flip the order.

‍

Before you ever look at a candidate’s resume, ask them to complete a short form with 2–3 open-ended questions. Focus on mindset, problem-solving, or past experiences.

‍

This way, you evaluate people based on how they think and approach challenges—not where they went to school or which companies hired them before.

‍

Only after you’ve seen how they think should you look at their background to validate skills or experience.

‍

Mistake #2: Telling Candidates Exactly What You’re Looking For

‍

It sounds harmless. You open the interview and say something like:

‍

“We’re looking for someone who’s highly proactive and thrives in a fast-paced environment.”

‍

Seems like a great way to set the tone, right?

‍

Actually, it’s a trap.

‍

The moment you tell candidates what you want, you give them a script to follow. Whether they’re a true fit or not, they’ll reflect your words right back to you.

‍

This creates false positives—people saying what you want to hear, not who they really are.

‍

The Fix: Let Them Show You

Don’t tell them what great looks like.

‍

Ask them to show you how they think.

‍

Instead of saying “We value ownership,” ask:

‍

“Tell me about a time when you had to take full ownership of a project. What happened, and what did you learn?"

‍

Look for patterns. Candidates with genuine accountability won’t need prompting. Their stories will naturally highlight initiative, ownership, and resilience.

‍

Mistake #3: Leading With Perks Instead of Fit

‍

In a competitive hiring market, it’s tempting to lead with benefits.

‍

“We’ve got a great culture, free lunches, and a ping-pong table in the office!”

‍

But perks should be a bonus, not a recruitment hook.

‍

If someone is drawn in by shiny benefits rather than the challenge or mission, they’ll leave as soon as something shinier shows up elsewhere.

‍

You risk attracting candidates who are more excited by surface-level extras than doing meaningful work.

‍

The Fix: Sell the Mission, Not the Massage Chair

‍

The best candidates don’t want gimmicks.

‍

They want impact.

‍

Start by framing the real challenge:

• What problem will they get to solve?
• How will this role help them grow?
• What will success look like 6 months in?

When you lead with purpose and alignment, the perks become a pleasant surprise—not the reason they say yes.

‍

Mistake #4: Screening for Skills Instead of Mindset

‍

Skills matter—but they’re not the full picture.

‍

In fact, most companies over-index on them.

‍

They treat the interview like a checklist of certifications, tools, or years of experience. But in fast-growing businesses, attitude beats aptitude every time.

‍

You can train someone on tools.

‍

You can’t train someone to take ownership, bounce back from failure, or handle ambiguity with maturity.

‍

The Fix: Hire for Grit, Coachability, and Ownership

‍

Shift your focus to what actually drives performance.

‍

Here’s what to look for:

• Grit: Do they push through when it’s hard?
• Self-awareness: Can they reflect on mistakes and learn?
• Initiative: Do they go beyond what’s asked?

Use behavioral questions and live challenges to observe these traits in action. Define what “great” looks like in your culture—and assess against that.

‍

Check for minimum skill requirements last.

‍

That one shift alone will widen your talent pool and improve your hiring results.

‍

Mistake #5: Letting Sunk Cost Bias Delay Tough Calls

‍

You’ve spent weeks hiring.

‍

You’ve trained them. Introduced them to the team. Maybe they even relocated for the role.

‍

So when things start to go wrong, you hesitate.

‍

“Let’s give them more time.”

‍

“Maybe they just need more support.”

‍

“We’ve already invested so much...”

‍

This is sunk cost bias—holding onto something simply because of what you’ve already put in.

‍

The cost of keeping the wrong hire isn’t just financial.

‍

It drags your team down, frustrates your top performers, and slows everything you’re trying to build.

‍

The Fix: Use the 90-Day Rule

‍

Every hire should be treated as a 90-day trial by default.

‍

Unless you see clear signs that they’re thriving—making an impact, aligning with your values, leveling up quickly—you have to consider that it’s not a fit.

‍

Don’t look for reasons to justify keeping someone.

‍

Look for evidence that it’s working.

‍

This mindset shift will save you from dragging out a problem hire for months (or years), which is where the real damage happens.

‍

Final Thought: Hiring Isn’t Luck—It’s a System

‍

Hiring well isn’t about intuition or experience. It’s about designing an interview process that works.

‍

And most of the pain companies feel during growth comes down to a lack of structure in hiring.

‍

Here’s what you now know:

• Resumes don’t tell the full story
• Candidates will mirror you if you lead too much
• Perks can attract the wrong people
• Mindset and ownership matter more than perfect experience
• Delaying decisions creates long-term pain

✅ Fix these five mistakes, and hiring becomes a competitive advantage—not a gamble.
