Reference check questions for customer service reps

A customer service representative interviews well almost by definition: they talk to strangers for a living. What the interview cannot show is the last call of a long day, from a customer who has called before about the same refund and is angrier this time. The team lead who listened to that call, and the quality analyst who scored it, can tell you how it went.

Contact centers measure almost everything, so a good reference can speak to handle time, quality scores, customer satisfaction and schedule adherence. Numbers alone can mislead in both directions: a low handle time can mean rushed customers, and a high one can mean a representative who fixes problems properly. Ask what was behind each number.

Who to ask

• A team lead or supervisor who reviewed the candidate’s metrics and listened to their calls or read their chats.
• A quality analyst or coach who scored their interactions and saw how they responded to feedback.
• A senior representative or escalation specialist who took the cases the candidate passed on and saw the notes that came with them.
• For a remote role, a supervisor who managed the candidate remotely, for how they worked with nobody nearby.

Questions to ask, by competency

Choose the competencies that matter most for the position and two or three questions from each. Ask every reference the same set, and when an answer is a rating, ask for the example behind it.

Difficult customers

The calls and chats that test a representative are the angry, repeated and impossible ones, and a team lead has heard them.

1. Tell me about a call or chat with an angry customer that you reviewed. What did the candidate say, and how did it end?
2. When a customer asked for something the policy did not allow, how did the candidate say no, and what did they offer instead?
3. When you listened to the call that came right after a hostile one, how did the candidate sound?

Resolution and account accuracy

A quick call that does not solve the problem comes back as another call, and wrong account notes cause the one after that.

1. How often did the candidate solve the problem on the first contact? When they could not, how did they set up the escalation?
2. Could another representative pick up a case from the candidate’s notes without calling the customer back to ask again?
3. Did the candidate follow identity verification and account security steps every time, even with a customer who was in a hurry or upset?

Quality scores and coaching

Quality reviews show how the candidate treats customers when nobody is listening live, and coaching shows whether they improve.

1. What score from one to five would you give the candidate’s call quality compared with the rest of the team, and what did the reviews usually point out? (rating)
2. When you coached the candidate after a call review, what changed in the calls that followed?
3. Did the candidate ever rush customers to keep their handle time down? How did you notice?

Schedule adherence and remote work

Contact centers schedule staff against the expected volume of contacts. A representative who logs in late or stretches a break leaves customers waiting in the queue.

1. How closely did the candidate keep to their schedule: logged in on time, with breaks and lunch taken as planned?
2. If the candidate worked from home, how did they stay reachable and productive without a supervisor in the room?
3. When contact volume spiked and you needed extra hours or a changed schedule, how did the candidate respond?

Written support

In chat and email, the customer judges the company by spelling, tone and whether the answer is complete.

1. How well did the candidate write to customers? Were their chat and email replies clear, correct and in your company’s voice?
2. How many chats could the candidate handle at once before their accuracy or tone slipped?

Close the reference

End every reference the same way: ask whether they would hire or work with the candidate again and why, what support would help the candidate do their best work, and whether there is anything else you should know. The general question bank explains why the first of these matters most.

Checks a reference does not replace

• Writing and typing, with a short chat or email exercise for written support roles. A reference describes past work; an exercise shows you the candidate’s writing now.
• Dates and job title with HR or the employer’s verification process, especially for contact center work done through an outsourcing company or a staffing agency.
• A background check, if the role gives access to payment or account data. When a third party prepares it, the FTC’s guidance says you need a written, stand-alone notice to the candidate and their written permission before you get the report.

Warning signs to follow up

• A supervisor who quotes the candidate’s handle time but cannot describe a single call they listened to.
• Mentions of skipped verification steps, or account notes that other representatives had to correct.
• Hesitation when you ask how the candidate took coaching after a poor quality review.
• References only from peers in the same queue, and no team lead or quality analyst.

One warning sign is a reason to ask another question, not a verdict. Reference check red flags covers how to check a concern fairly.

Questions to leave out

Ask only about the work. Before an offer, the EEOC’s guidance says an employer may not ask a third party, such as a former employer, any question it could not ask the candidate directly. Leave out health, medical leave, age, family plans and other protected characteristics. What to leave out has the full list.
