Reference Checks That Actually Work
References are goldmines of information—if you ask the right questions. Here's how to get real answers.
Reference checks are often treated as formalities. A quick call, some generic questions, check the box. This is a mistake. Done well, reference checks reveal what interviews can’t—how someone actually performs over time.
Why References Matter
Interviews Are Limited
Interviews assess:
•
How someone presents themselves
•
Performance under artificial conditions
•
A snapshot in time
References reveal:
•
How they actually work day-to-day
•
Patterns over extended periods
•
Real performance, not rehearsed answers
Red Flags Don’t Show in Interviews
Problematic employees often interview well:
•
Great communicators who don’t execute
•
Confident people who blame others
•
Charming personalities with toxic patterns
References catch what interviews miss.
When to Check References
After Strong Interview, Before Offer
Reference checks should be:
•
Late enough that you’re serious (respect candidate’s time)
•
Early enough that you can walk away
Before Extending Written Offer
Once you extend an offer, you’ve lost leverage:
•
Harder to rescind
•
Creates legal complications
•
Burns goodwill
Check references first.
Getting Good References
Beyond the Provided List
Candidates provide references who will say good things.
Better sources:
•
Ask references for other references
•
LinkedIn connections you share
•
Former colleagues you know
•
Backchannel through your network
Ask candidates: “Who else worked closely with you?”
The Right People to Call
Best references:
•
Direct managers (most important)
•
Peers who worked closely with them
•
People they managed
•
Cross-functional partners
Less useful:
•
HR contacts
•
Brief acquaintances
•
Only friends
Getting Them to Be Honest
People are reluctant to say negative things:
•
Fear of legal issues
•
Don’t want to hurt the candidate
•
Path of least resistance is positive
Create safety:
•
Promise confidentiality
•
Share that you’re genuinely trying to help them succeed
•
Ask about context, not just judgment
Questions That Work
The Opening
Build rapport first:
•
How do you know [candidate]?
•
How long did you work together?
•
What was your relationship?
Get context before diving in.
Performance Questions
Specific, not general:
“Can you tell me about a project [candidate] owned? What happened?”
“What were their key contributions?”
“Where did they struggle?”
“How did they handle [challenge]?”
Comparison Questions
Calibrate their assessment:
“On a scale of 1-10, how would you rate their overall performance?”
“How do they compare to others in similar roles?”
“Would you hire them again? For what role?”
The Key Questions
These reveal the most:
“What would I need to do to help them succeed here?”
•
Reveals development areas without being negative
“What type of environment do they thrive in? Struggle in?”
•
Culture fit indicators
“If there’s one thing I should know about working with them, what is it?”
•
Opens door to both positive and negative
“Is there anyone else I should speak with?”
•
Often reveals more balanced perspectives
The Silence Trick
After they answer, pause. Wait.
People fill silence:
•
They’ll add nuance
•
Qualify their statements
•
Sometimes reveal what they were holding back
Don’t rush to the next question.
Reading Between the Lines
What Silence Means
If a reference is:
•
Hard to schedule → They’re avoiding
•
Very brief → They have concerns
•
Won’t elaborate → There’s more they’re not saying
Faint Praise
“They were fine.”
“They did their job.”
“No complaints.”
Faint praise is often worse than criticism. Great employees get enthusiastic references.
Qualifications and Caveats
“They’re great, but…”
“They were good in that role, though…”
“It depends on the situation…”
Listen closely to what follows the “but.”
Enthusiasm Levels
Strong signal:
•
“They were amazing”
•
“I’d hire them back in a second”
•
“One of the best I’ve worked with”
Weak signal:
•
“They were solid”
•
“They got along with people”
•
“They were professional”
What’s Not Said
Notice what they avoid:
•
Asked about ownership, they talk about teamwork
•
Asked about leadership, they talk about technical skills
•
Asked about conflict resolution, they change the subject
Manager vs. Peer References
What Managers See
•
Performance against goals
•
How they handle feedback
•
Reliability and delivery
•
Growth over time
What Peers See
•
Day-to-day collaboration
•
How they treat people without authority
•
Real working style
•
Whether people want to work with them
What Reports See
•
Leadership style
•
How they handle power
•
Support for team growth
•
Pressure behavior
Get all three perspectives.
Backdoor References
When to Use Them
You share connections with the candidate. Should you reach out?
Yes, when:
•
You’re serious about the candidate
•
The connection is relevant (worked together)
•
You can be discreet
No, when:
•
It could hurt the candidate’s current job
•
The connection is too distant to be useful
•
You’re just fishing
How to Do It Respectfully
“I’m speaking with [candidate] about a role. I noticed you overlapped at [company]. Would you be open to sharing your experience?”
Be direct about what you’re doing.
Candidate Permission
For current employers or sensitive situations:
•
Ask candidate first
•
They may have reasons for confidentiality
•
Respect their situation
Red Flags
Immediate Concerns
•
Reference won’t call back
•
Very short, guarded answers
•
“I’m not allowed to say much” (often means there’s a lot to say)
•
Stories that don’t match candidate’s version
Patterns to Watch
•
Different references tell different stories
•
No manager references available
•
All references are friends, not colleagues
•
Left multiple jobs after short tenure
Deal Breakers
•
Integrity issues mentioned
•
“I wouldn’t hire them again”
•
Consistent feedback about the same problem
•
References who won’t speak on the record
What to Do With Information
Positive References
Move forward with confidence:
•
Consistent enthusiasm
•
Specific examples of success
•
Would rehire without hesitation
Mixed References
Dig deeper:
•
What’s the pattern?
•
Are concerns relevant to this role?
•
Can you mitigate the issues?
Negative References
Options:
•
Walk away (often the right choice)
•
Discuss directly with candidate
•
Get more data points
Don’t rationalize: If references are bad, believe them.
Common Mistakes
Not Doing Them
Skipping because interviews went well.
Fix: Always check references. No exceptions.
Only Checking Provided References
Taking the candidate’s list at face value.
Fix: Build your own reference list too.
Generic Questions
“What was it like working with [candidate]?”
Fix: Ask specific, probing questions.
Not Listening for Nuance
Taking everything at face value.
Fix: Listen for tone, enthusiasm, what’s not said.
Checking Too Late
After extending the offer.
Fix: Check before any offer is made.
