If you're struggling to break into the trades, sending applications, hearing nothing back, or not knowing what employers want, you're not alone. Many aspiring HVAC techs, plumbers, and mechanical workers face the same frustrating wall, especially when starting out.
At Harold Brothers, we've worked with hundreds of apprentices, journeymen, and foremen across New England. We’ve seen firsthand what separates the hired from the overlooked and, more importantly, how newcomers can set themselves up for long-term success.
In this article, you’ll learn what hiring managers are looking for in candidates, what you can do to stand out (on paper and in person), and how to build a career path that moves you from apprentice to foreman with confidence.
What Hiring Managers Are Really Looking For
Before you step onto a job site, your attitude, effort, and preparation already say a lot about you. Hiring managers in the trades aren’t just looking for people who can turn a wrench; they’re looking for dependable team members who take pride in their work, show up ready to learn, and care about doing the job right.
1. Reliability and a Strong Work Ethic
The trades are built on trust. If you show up on time, follow instructions, and take safety seriously, you’ve already made a strong impression.
2. Willingness to Learn and Take Direction
No one knows it all on day one. Managers are looking for people who ask questions, listen to feedback, and want to keep getting better.
3. A Positive, Team-Oriented Attitude
Most jobs require coordination with electricians, GCs, engineers, or other trades. Respect and communication go a long way.
4. A Commitment to Jobsite Safety
Companies like Harold Brothers prioritize safety every day, and even give out awards for safe behavior. Being mindful of your surroundings and following protocols is a must.
How to Make Your Application Stand Out
Even in the trades, how you present yourself on paper matters. A clear, simple resume can help you stand out from other applicants. Be sure to include your contact information, a summary or short goal statement, and any relevant work experience, even if it’s not in the trades.
Jobs like construction, landscaping, or home repairs show that you’re comfortable with tools and physical labor. Also, list any certifications you’ve earned, such as OSHA training, safety credentials, or trade school completions.
A cover letter doesn’t need to be long. Just a few thoughtful sentences that explain why you’re interested in the trades, what excites you about the company or field, and your willingness to learn and grow can make a strong impression.
Finally, if you haven’t heard back after about a week, it’s perfectly okay to follow up. A polite follow-up message shows initiative, something hiring managers always appreciate.
What to Bring to an Interview for a Skilled Trades Job
Showing up prepared for an interview helps you make a strong first impression. Along with a good attitude and clean work clothes, bring copies of any important documents that show your qualifications.
If you’re an apprentice or journeyman, bring a copy of your license. You should also bring your OSHA card and any additional certifications you’ve earned, like a Hot Work permit, Mobile Elevating Work Platform (MEWP) card, or confined space training. If you have a resume or letter of recommendation, bring a printed copy of those, too.
Having these documents in hand shows that you take the opportunity seriously and are ready to get to work. Many hiring managers will use this information to verify your credentials and fast-track your onboarding if you're the right fit.
