What was the toughest situation you've had fixing a car?

"My customer's compressor melted and damaged one of the engine belts in the process. I had to replace the compressor and took care not to affect too many other parts of the car to keep the cost low. I replaced the belt for the safety of the customer, but ended up keeping everything under 800 for the customer."

Car problems can be complicated. Sometimes the toughest part of a job is defining the problem. Sometimes it's tricky actually to fix it.

When you prepare for your interview, think about how you have solved challenging problems in the past. What made them so difficult? Why did you follow those particular steps to resolve it?Describe a situation that took research and time before you came to a solution.

"A customer came to me and said the car was shaking whenever it idled at red lights. I thought it could be the engine mount, so I replaced that. But the problem persisted. I did some research, and it turned out to be an electrical problem. Through checking the different codes, I discovered the catalytic converter needed to be replaced, as well."
