Top Interview Questions for Automotive Mechanics

The automotive industry is one of the largest and most stable sectors in the U.S. economy, and becoming an automotive mechanic offers a rewarding, hands-on career path with plenty of opportunities for advancement.

Whether you're interested in working at local repair shops, car dealerships, or even starting your own garage, this guide will walk you through everything you need to know.

What do mechanics do?

Automotive technicians are responsible for diagnosing, maintaining, and repairing vehicles of all types—from compact cars to light trucks and SUVs. Their work involves inspecting brake systems, replacing worn parts, and performing routine services like oil changes. Many mechanics work in repair shops or at car dealerships, but others prefer to start their own repair shop.

Mechanics work with a variety of tools and diagnostic equipment. They often use computerized systems to identify issues and ensure the car is functioning properly. In today’s rapidly evolving automotive industry, mechanics are expected to stay current with new technologies, especially in hybrid and electric vehicles.

Below, you will find practical steps you can take today to start your path to becoming an auto mechanic.

6 Steps to becoming a car mechanic

Starting a new career path can be challenging, so we outlined 6 practical steps you can take to jump-start your career.

1. Do your homework

Before you start your career, it is wise to consider if this is the right job for you. Will it pay enough to support your needs? Will you be able to keep up with the physical demands of the job? These are just two of the questions you need to ask yourself before moving forward.

How Much Do Automotive Mechanics Make?

According to the U.S. Bureau of Labor Statistics, the average salary for automotive service technicians and mechanics in 2024 was approximately $49,670 per year, or about $23.88 per hour. However, salaries can vary based on several factors such as:

• Location: Mechanics in cities or states with a higher cost of living tend to earn more.
• Certifications: Holding ASE certifications or specializations can boost income.
• Experience: Entry-level technicians typically earn less than seasoned professionals.
• Industry: Working at car dealerships or as a mobile mechanic can pay differently than working in a small auto repair shop.

2. Training and education

Pursuing the right education, certifications, and training programs will set you on the right path to a successful career. Each path has unique benefits but it is best to select the path that will help you achieve your career goals.

Do I need to go to school to become a mechanic?

While formal training is not always required, it is highly recommended. Employers in both independent repair shops and dealerships prefer candidates with a solid educational background and certifications. If you opt not to pursue formal education, you will need to find a personal connection or an apprenticeship program where you can learn while working.

How long will it take to become a mechanic?

The timeline to becoming an auto mechanic depends on the education path you choose. In total, it may take anywhere from 6 months to 4 years to become job-ready, depending on the path and certifications you pursue. Here are the most common routes:

• High School Diploma or GED: Most mechanic jobs require at least a high school diploma or equivalent.
• Vocational Schools or Trade Schools: These typically offer certificate programs lasting 6 months to 1 year, giving students a fast track into entry-level roles.
• Community College or Associate Degree: Completing an associate degree in an automotive technology program usually takes about 2 years and provides a deeper understanding of vehicle systems.
• Apprenticeships: These allow students to earn while they learn and may last 2 to 4 years.
• On-the-Job Training: Some auto mechanics begin their careers with no formal education and learn through hands-on experience at a repair shop or dealership.

3. Complete certifications

The most respected credential in the field is the ASE certification, offered by the National Institute for Automotive Service Excellence. Mechanics can earn ASE certification in areas such as engine repair, brake systems, electrical systems, automatic transmission, and heating/air conditioning.

To become ASE certified, you’ll need at least two years of work experience or a combination of formal training and on-the-job training. You’ll also need to pass one or more certification exams. Mechanics who pass tests in all major areas and have the required work experience can earn the title of Master Technician.

Being ASE certified shows employers and customers that you're a professional who meets industry standards. Many employers pay higher wages to certified auto mechanics, and some dealerships require ASE credentials for certain positions.

4. Prepare for your interview

Finding the right shop to start your career at can be a daunting task. It is often easiest to start at an express shop so you can get your feet wet before pursuing your career goals. Once you have applied to a shop, it is time to start preparing for the interview.

Mechanic Job Interview Questions

Whether you're aiming for a position at a dealership or local garage, be prepared for a formal interview. Here are common questions you may encounter:

• Tell me about yourself and your experience as an automotive technician.
• Why do you want to work for our company/shop?
• How do you stay up to date with new automotive technologies and repair techniques?

• What certifications do you currently hold (ASE, manufacturer-specific, etc.)?
• Are you comfortable working weekends, evenings, or overtime if needed?

When answering, emphasize your hands-on training, work experience, and your commitment to continuous improvement. Don’t forget to highlight soft skills like teamwork, communication, and adaptability.

5. Utilize modern tools

The modern repair shop has embraced new technology to help improve efficiencies and revenue. Strive to have a solid understanding of modern diagnostic tools, apps, and software so you can hit the ground running.  Another way to stand out to your future employer is to already have experience with their shop management system, so they don’t have to train you as much.

6. Get your hands dirty

Let the fun begin! Once you have landed your first job, learn to fail fast and ask questions as you meet more experienced technicians. Ask yourself each week if you are enjoying your job and if you think this is still the right career path for you. Don’t forget to make connections in the industry to boost your network and career path.

What Should Be Included in an auto repair shop receipt?

1. Shop contact information

The first thing on your receipt should be your auto repair shop’s full contact information. This builds credibility and ensures customers know how to reach you if follow-up is needed.

What to include:

• Shop name
• Address
• Phone number
• Email address
• Website (if applicable)
• Business logo for branding

A well-organized template with your logo and contact information at the top makes your documents look professional and trustworthy.

2. Customer Information

Next, capture the customer’s name and their contact information. This ensures the receipt is tied to the correct individual and helps with record-keeping for recurring car repair clients.

What to include:

• Customer's name
• Address
• Phone number or email

This section ensures your auto repair business can easily identify who the repair services were for and reach them quickly if needed.

3. Date of service and invoice number

Every mechanic receipt needs to include the date of service and a unique invoice number. This creates an accurate timeline and helps organize documents chronologically for tax reporting, audits, or warranty purposes.

What to include:

• Date the service was completed
• Unique invoice number
• Optional: technician’s name or initials

4. Vehicle information

For any automotive service, tying the repair order to a specific vehicle is a must. This helps with real-time service tracking, vehicle history reporting, and future maintenance recommendations.

What to include:

• Year, make, and model
• Vehicle Identification Number (VIN)
• License plate number
• Mileage at the time of service

5. Description of services performed

This is the heart of the receipt. Clearly outline what repair work was done and what repair services were provided. The more detail, the better.

What to include:

• Itemized list of services
• Description of each job (e.g., “Brake pad replacement” or “Engine diagnostic”)
• Associated labor costs for each service
• Cost of parts

6. Parts and material breakdown

An itemized list of parts and materials used in the repair work is just as important as the labor section. This transparency helps avoid disputes and gives your customer clarity on what they’re paying for. Most auto repair shops don’t show the markup percentages on parts but you can if you want to maximize transparency.

What to include:

• Part name and number
• Quantity used
• Cost per unit

7. Balance Due and Payment Summary

Now it’s time to outline the financials, from the subtotal to the total amount. This section should also include the total cost, taxes, discounts, and any payment options you accept.

What to include:

• Subtotal (before tax)
• Taxes (state/local)
• Any discounts or promo codes
• Total amount due
• Payment methods accepted (e.g., cash, credit card, financing)
• Amount paid and remaining balance
• Due date for final payment, if applicable

Including this section with clear headings avoids confusion and can prevent billing issues down the line. It also ensures the receipt can function as proof of payment. Lastly, this is a great place to feature your financing options (if applicable).

8. Warranty Information

Warranty details protect both your shop and your customer in case a part fails or a job needs to be redone. If your auto repair shop offers any warranty, you need to clearly list what’s covered and for how long.

What to include:

• Warranty length (e.g., 12 months or 12,000 miles)
• What is and isn’t covered
• Instructions for claiming the warranty
• Any third-party coverage (for example, if a part manufacturer offers a separate warranty)

This section should be written in clear, non-technical language to help customers fully understand their protections. You may want to include a signature line for the customer to acknowledge receipt of the warranty.

9. Streamline receipts

Creating receipts and invoices by hand can be tedious but Tekmetric streamlines that for you. Tekmetric can help you build faster estimates and take payments digitally with our auto repair estimate software.

Some of our features include:

Final Thoughts

A well-documented auto repair receipt protects your shop, helps your customer feel confident, and sets the tone for a long-term relationship. From capturing accurate customer information to detailing every repair service, your mechanic receipt should leave nothing to guesswork.

Don’t just think of it as paperwork—think of it as part of your shop’s customer experience. With a little extra attention to your receipt process, your auto repair shop can stand out as a professional, transparent, and customer-first automotive service provider.
