The best CSR interview questions contractors can use are the ones that simulate a real call, not the ones that ask about strengths and weaknesses. A garage door CSR lives or dies on three things: staying calm with a stressed caller, capturing details accurately, and booking the window without handing the caller a reason to shop around. Test those directly.
Here's the set that does it, plus the role-play that tells you more in five minutes than an hour of conversation.
Start with the questions that reveal phone instincts
Skip "tell me about yourself." Open with questions that force the candidate to show you how they think on the phone:
"A caller says their car is trapped in the garage and they're late for work. Walk me through exactly what you say." You're listening for empathy first, then questions, then a commitment. If they start with "I'd ask for the address" before acknowledging the panic, that's a tell.
"What information do you need from every caller before you hang up?" The right answer: name, callback number, address, and what's wrong with the door. Missing any one of those costs you jobs.
"A customer calls furious that a tech hasn't shown up. What do you do?" You want "acknowledge, get the details, give a specific next step" — not "transfer them to the owner."
"How do you handle a caller who just wants a price over the phone?" There's no single right answer, but a good candidate knows the goal is booking the service call, not winning a quoting contest.
"Tell me about a time you dealt with someone yelling at you on the phone." Anyone who has done phone work has this story. Anyone who hasn't will show you how they'd improvise — which is also useful information.
The role-play that settles it
This is the single most useful tool in the interview. Do it live, in the room or on a call:
You play the customer. Pick a real scenario from your shop: broken torsion spring, door off track, opener dead with the car inside.
Give them one line of setup: "You answer the phone at my shop. Go."
Be a little difficult — rushed, vague about what's wrong, impatient.
Watch for three things. Did they get the name and number early, before you could "hang up"? Did they book a specific window instead of saying "someone will call you back"? Did their tone stay steady when you pushed?
A candidate who does those three things naturally can learn your schedule software in a week. A candidate who can't will cost you jobs no matter how friendly they are. Most owners who've hired phone staff will tell you the role-play predicts performance better than the resume ever does.
Red flags worth catching in the interview
They talk about the job as "just answering phones." They'll treat it that way, and your callers will hear it.
No questions about your shop. A good CSR candidate asks how many techs you run, what your service area is, what a typical day of calls looks like. Curiosity about the operation predicts engagement.
Blame stories. If every past job story ends with a terrible boss or terrible customers, your customers are next.
Discomfort with the role-play. If they freeze when it's practice, imagine a real 7 AM emergency call.
What this means for your shop
Run tight interviews because a bad CSR hire is expensive — receptionist turnover costs you the rehiring, the retraining, and the coverage gap in between. Before you post the job, pair these questions with a copy-ready garage door CSR job description so candidates know exactly what the role demands.
And consider whether you need the hire at all yet. Many shops find the phone problem isn't a people problem — it's a coverage problem. Ava answers every call 24/7, triages emergencies like the trapped-car call above, captures the details every time, and sends you an instant summary. Some owners hire a CSR for daytime counter and dispatch work and let Ava own the phones entirely. Others run Ava first and discover the hire can wait a year.
