Question 1

Walk me through how you'd diagnose an intermittent check engine light with a misfire code.

Accepted Answer

This is the core of the job. They want to hear a process, not a guess, and they're listening for whether you replace parts before you prove the fault. Start with the customer's concern: when it happens, cold or warm, under load or at idle Pull codes and freeze frame data, then check for technical service bulletins Look at live data and misfire counters, swap a coil or plug to see if the misfire follows it Check fuel trims, injector and wiring before calling it a bad part Verify the repair with a road test that recreates the original conditions

Question 2

Tell me about a comeback you had. What went wrong and what did you change?

Accepted Answer

Every tech has comebacks. They want to know if you own them or blame the part, the advisor or the customer. Name a real job and what came back Say plainly what you missed, like skipping a torque spec or not verifying the fix Explain how you fixed it the second time Describe the habit you built so it doesn't repeat

Question 3

How do you feel about flat-rate pay?

Accepted Answer

If the shop runs flat rate, they need to know you understand it and won't quit the first slow week. Show you know how book time works and that efficiency is on you Mention how you keep hours up: staying organized, prepping parts, not waiting on the advisor Be honest about what you need from them, like a fair share of the good work Ask how they dispatch jobs so it doesn't sound like you're only thinking about pay

Question 4

What goes on the repair order after you finish a job?

Accepted Answer

Clean notes protect the shop on warranty claims and help the advisor explain the bill. Messy notes cost everyone money. Mention the three Cs: concern, cause, correction Include the codes, test results and readings that proved the fault Note anything else you saw that the customer should know about Write so the advisor can explain it without walking out to your bay

Question 5

Which ASE certifications do you hold, and which are you working on?

Accepted Answer

Certifications affect what work they can give you and sometimes your pay. They also show whether you invest in yourself. List what you have by name, not just a count Say which test is next and when you plan to sit for it Mention EPA refrigerant certification if you have it Tie your next test to the work this shop does

Question 6

What's the hardest electrical problem you've tracked down?

Accepted Answer

Electrical work separates line techs from the ones who get the problem cars. They want to see if you can read a wiring diagram and use a meter. Describe the symptom and why it was tricky Say how you used the wiring diagram and which circuits you tested Mention voltage drop testing or a lab scope if you used them Give the actual cause, like a chafed wire or a corroded ground

Question 7

What tools do you own, and what's in your box that you use every day?

Accepted Answer

They need to know you can start working on day one without borrowing, and how seriously you take the trade. Give an honest picture of your hand tools and box Name your meter and any scan tool you own Say what you plan to add and why Don't exaggerate, because they'll see your box the first morning

Question 8

A service advisor sells a job at a price, and you find it's a bigger repair than quoted. What do you do?

Accepted Answer

Tech and advisor friction is the most common fight in any shop. They want someone who solves it without drama. Stop and document what you found before going further Go to the advisor right away with photos or measurements Let the advisor call the customer, since that's their job Don't do unapproved work to prove a point

Question 9

How do you stay safe working on hybrid or electric vehicles?

Accepted Answer

High-voltage systems can hurt people. Shops want techs who respect the procedure, not ones who wing it. Mention following the manufacturer's service disconnect procedure Talk about rated gloves, checking them before use, and verifying zero voltage Say you'd flag it if you haven't had training on that system Mention any hybrid or EV training you've had

Question 10

A customer's car is on your lift and you notice worn brakes they didn't ask about. How do you handle it?

Accepted Answer

They're checking whether you'll recommend work honestly. Shops need the sales, but they also need customers who trust them. Measure it and write down what you found Pass it to the advisor with the measurement, not a guess Separate safety items from things that can wait Never oversell to pad your hours

Question 11

How do you keep up with new systems like driver assistance cameras and radar?

Accepted Answer

Cars change faster than most techs' training. They want to know you'll keep learning without being pushed. Name a real source: factory training, online courses, ASE study, tech forums Mention any ADAS calibration or module programming you've done Say what you'd like to learn next Ask what training this shop offers

Question 12

Why are you leaving your current shop?

Accepted Answer

Techs move a lot. They want to know you won't leave them just as fast, and that you won't trash your old shop. Give a real, forward-looking reason, like better diagnostic work or training Keep it short and professional Connect it to something specific about this shop
