Reference check questions for customer service agents

A reference check is the last look before you make an offer. It will not tell you how someone writes to customers. Your test already did that. It tells you how they behaved over months: whether they showed up, took feedback and kept to the rules when nobody was checking.

Here is when to check, how to make sure the reference is real, twelve questions to ask, and what to do when an applicant has no reference at all.

When to check

• At the end. After the test and the call, for your final one or two people. Checking everyone wastes your time and theirs.
• With their permission. Ask the applicant first, and tell them who you will contact.
• With the right people. Ask for two references, ideally a team lead or supervisor from a support job. A co-worker is a weaker reference. A friend or relative is not one.

Make sure the reference is real

A reference can be a real supervisor, or a friend reading from a script. These checks help you tell the difference:

• Find the company yourself. Look up the company's website or public page and reach the reference through it where you can, not only through the number the applicant gave.
• Look at the email address. An address on the company's own domain is a good sign. A free email address is not proof of anything, since many small businesses use one, but it is worth one more question.
• Match the details. The dates and the job title should match the application.
• Ask a question only a real supervisor would know. "How many people were on the team?" or "Which tool did you use for chats?" A real supervisor answers at once.

Some larger employers, contact centers included, confirm only dates and job title, through their HR team. That is a normal answer, not a bad sign. Filipino applicants can often show a Certificate of Employment (COE) from a past employer. It confirms dates and position, not how well someone worked.

Treat anything odd as a question for the applicant, not a verdict.

The twelve questions

Start with the basics

1. "How do you know [name], and for how long?"

2. "What was their job when you worked together?"

These confirm the reference was in a position to judge, and that the job title is real.

The work itself

3. "Did they handle chat, email or both? How many conversations at once?"

Compare the answer with what the applicant told you.

4. "Would you have trusted them with your most upset customers? Why or why not?"

This gets a more honest answer than "Were they good with customers?"

5. "Tell me about a time a customer was unhappy with them. What happened?"

Every agent has one. A reference who cannot think of any may not have known their work well.

6. "How did they handle things they were not allowed to do alone, like refunds or account changes?"

You are listening for someone who followed the rules and passed things on properly.

Reliability

7. "How was their attendance, compared with the rest of the team?"

Ask about the record, not the reasons. Do not ask about health.

8. "For remote work: what happened when their internet or power went out?"

Listen for someone who told the team quickly and had a backup.

Growth

9. "Tell me about feedback you gave them. What did they do with it?"

The best answer describes a change that stuck.

10. "What would a new manager need to know to get the best from them?"

This is a kind way to ask about weak spots, and it often gets a useful answer.

Close

11. "Why did they leave?"

Compare the answer with the applicant's own.

12. "Would you hire them again for the same job?"

Then stay quiet for a moment. A quick, warm "yes" means a lot. A long pause, or "It would depend," is worth a gentle "On what?"

How to read the answers

• Specific beats glowing. "She cleared the email queue every Friday without being asked" tells you more than "She was amazing."
• Notice faint praise. "He was always on time," and nothing else, can be a polite way of saying little else was good.
• Weigh it with the rest. A reference is one source. The work sample and the call are still the main evidence.

What not to ask a reference

The same limits apply as in your own interview. Do not ask about age or birth date, marital status, family plans, religion or health. "Was she often sick?" is out. So is "Is he planning to have kids?"

If your applicants are in the Philippines, the Data Privacy Act (Republic Act No. 10173) sets rules for collecting and using personal information, and lists age and marital status among "sensitive personal information." Telling the applicant who you will contact, and asking first, is a good habit wherever you hire. What you can't ask Filipino applicants covers the age rule for job applications in full.

When there is no reference

Some good applicants have never had a support job, or cannot reach a past employer. That should not end their chances.

• Ask for another kind of reference. A teacher, an adviser from a school group, a freelance client, or the lead of a volunteer group can still speak to reliability and effort.
• Lean on the work sample. If their test was strong, it already shows the most important thing.
• Offer a short, paid trial. A first week with every reply reviewed tells you more than any reference could.

A note sheet to copy

Applicant: [name]          Reference: [name, role, company]
How I reached them: [company website / number from applicant]
Dates and title match the application: [yes / no / not given]

Q4  Trust with upset customers:
Q5  A customer who was unhappy:
Q9  Feedback and what changed:
Q12 Would hire again: [yes / pause / no], and why:

One thing to ask the applicant about:

Where this fits

If you use HireFlow, everything before this step sits in one place: each applicant's test replies with their scores and reasons, your messages with them, the interview, and the papers you ask for after the hire. The reference check is the one step you do outside it, by phone or email.

In short

• Check references last, for your final one or two, with the applicant's permission.
• Ask for a supervisor from a support job, and reach them through the company where you can.
• Ask for stories, not ratings: an upset customer, a rule they held, feedback they used.
• End with "Would you hire them again?" and listen to the pause.
• Leave out age, birth date, marital status, family, religion and health.
• No reference is not a no. Use another kind of reference, the work sample or a short paid trial.
