The Reference Check Nigerian Companies Outsource to HR and Why That’s Backwards

There is a moment in most Nigerian hiring processes that feels like diligence but produces almost nothing useful.

HR contacts two or three references the candidate has provided. Confirmation of employment dates and job titles is received. The checks are noted as complete. The candidate joins.

What was conducted was a compliance activity. What was needed was a diligence activity. The two are not the same, and treating them as equivalent is one of the most reliable predictors of hiring failure available in any process.

Because the reference check, done correctly, is one of the most predictive assessment tools available anywhere in the hiring process. And it is being systematically wasted.

What Reference Checks Are Actually For
The purpose of a reference check is not to verify that someone worked where they say they worked. Background verification services do that more efficiently.

The purpose of a reference check is to get the honest assessment of someone who has directly managed or worked closely with the candidate: an assessment that will tell you things the candidate cannot tell you about themselves, and things the interview process is structurally unable to reveal.

Research consistently shows that structured reference conversations with former direct managers are among the most predictive assessment methods available, significantly more predictive than behavioural interviews, and comparable to work sample tests in their ability to forecast actual job performance. This is not widely reflected in Nigerian hiring practice. If it were, reference calls would be conducted by the hiring manager, not HR, and they would happen before the offer rather than as a condition of it.

The HR Reference Check vs. The Manager Reference Check
An HR department confirming employment dates and a former manager speaking candidly about a candidate’s work is the difference between a passport photo and a character witness.

HR can tell you: this person worked here from this date to this date, in this role, left in good standing. This information adds almost nothing to your hiring decision. The candidate’s CV already told you this.

A former direct manager, speaking candidly in a conversation clearly framed as professional rather than personal, can tell you: how this person performed under pressure, what their specific strengths were, where they struggled, how they handled feedback, what the team dynamics were like when they were involved, and whether the manager would hire them again given what they now know.

That last question is the most informative single question in any reference conversation. And it is not the answer itself that tells you the most. It is the pause before the answer. The qualifications. The shift in tone. The answer that is technically affirmative but contextually conditional. “They were very good in certain contexts.” The former manager who says that has told you something that no interview question would have surfaced.

The Specific Questions That Surface What You Need to Know
Most reference calls in Nigerian hiring practice, even when they do reach former managers, ask the wrong questions. “What were their strengths?” “What were their weaknesses?” “How did they get on with the team?” These are so standard that most managers have developed reflexive answers that reveal almost nothing.

The questions that produce genuine signal are the ones the reference did not prepare for.

“Tell me about a time when this person was asked to do something they disagreed with. How did they handle it?” This question surfaces the candidate’s relationship with authority and their ability to constructively push back, or their tendency to comply without engagement.

“What would you say are the conditions under which this person does their best work? And the conditions under which they struggle?” This gives you specific environmental information you can map against what your organisation actually looks like.

“On a scale of 1 to 10, how would you rate their technical capability in this specific skill? And what would it take to get them to a 10?” The number is less important than the explanation of the gap. “A 7 on Python because they had not worked with asynchronous frameworks at this level” tells you something specific and actionable.

“If you were building a new team tomorrow and had an open role, would you make an offer to this person?” The former manager who says yes without hesitation is giving you a meaningful signal. The one who says “it depends on the role” has given you the beginning of a more informative conversation.

When to Do It and Who Should Do It
The structural change that transforms reference checks from administrative compliance to genuine diligence is simple: the hiring manager conducts them, before the offer is extended, with candidates’ former direct managers, not HR contacts the candidate has pre-approved.

The timing matters because a reference check conducted before the offer is extended has decision influence. A reference check conducted after the offer as a condition of employment is a risk assessment with limited response options. If it surfaces something significant, the company is in a difficult position: the candidate may have already resigned from their current role, and withdrawing the offer creates legal and reputational exposure disproportionate to whatever was learned.

The conversation should take 20 minutes. It should be structured but conversational. It should be conducted by someone who knows the role well enough to evaluate what they are hearing, which is why hiring managers, not HR generalists, should run it.

This is not a significant investment of time relative to the cost of the hiring decision it informs. It is a reallocation of reference check responsibility from a function that cannot use the information effectively to a function that can.

The Bottom Line
The companies that use reference checks correctly have a systematic advantage over those that do not, because they are accessing a layer of candidate information that their competitors are filing away in an HR compliance folder and never reading.

The reference check is not a formality. It is one of the most predictive tools available in any hiring process and it is being systematically underused because it has been delegated to a function that is structurally unable to do anything useful with the information it collects.

The fix is not more reference checks. It is better ones: conducted by the right person, with the right questions, at the right point in the process. The 20-minute conversation that happens before the offer is extended is worth more than the four-round interview process that preceded it.

Revent Technologies conducts structured reference verification as part of every placement, covering both employment verification and direct manager conversations, so the candidates you meet have already been checked, not just checked off.
