How to Ace Your Next Interview (A Guide for Plumbers)

Preparing for Your Dream Plumber Job Interview

If you have an interview coming up for your dream plumber job, use this guide to give yourself the best chance of success. These tips come from an experienced plumbing recruiter who knows firsthand what employers look for when hiring plumbers.

Nailing an interview boils down to preparation, confidence, and etiquette. Master these three areas, and the job is yours. Remember, they called you for an interview because they want to hire you. On paper, you are the candidate they want. Now, you need to show them that you are even better in person.

1. Preparation

Research the Company:

  • Visit the company’s website and check out their social media pages (Facebook, Twitter, Instagram, etc.).
  • Knowing about the company shows you are genuinely interested in them, not just any job.
  • Mention specific things you noticed, like team events, to show your engagement.

Anticipate Their Questions:

  • Be prepared for common interview questions. Check out our article, “27 Interview Questions To Ask a Plumber.”

Prepare Your Questions:

  • Bring your own questions to ask. Refer to our article, “5 Questions To Ask When Interviewed for a Plumber Job.”
  • Remember, you are also interviewing them to ensure the job fits your needs.

2. Confidence

Sell Yourself:

  • Many plumbers are uncomfortable selling themselves, but this is crucial in an interview.
  • Highlight your skills, accomplishments, and any special training you have completed.
  • Mention any relevant experience, especially if it matches the type of plumbing work the company does.

Avoid Overconfidence:

  • Be confident but not cocky. Ensure they know why you’re a great fit without coming off as arrogant.

3. Etiquette

Dress Appropriately:

  • Wear dress pants, a button-up shirt, and dress shoes.
  • Remove piercings for the interview, as some companies consider them a safety issue.
  • If you come straight from work, inform them beforehand. Showing up in work attire is acceptable if they are expecting it.


  • Arrive on time. Being late can be a dealbreaker.


  • Avoid trash-talking previous employers; it can make you seem like a complainer.
  • Thank the interviewers for their time.


  • Send a follow-up email thanking them for the interview.
  • Express your continued interest in the role, recap why you are a good fit, and provide references.

Interview Do’s and Don’ts


  • Discuss safety, a top priority for hiring managers.
  • Be well-prepared and polite.
  • Sell yourself effectively.
  • Show genuine interest in the job before you leave.


  • Trash-talk previous employers.
  • Bring up salary unless they ask first.
  • Be overly arrogant; be confident but humble.
