The Utilities Industry

Before we proceed to what companies are in the public utilities field, let’s have a keen understanding of what the public utilities sector is all about and what kind of companies are involved in offering these essential public services.

Utility companies are large corporations that provide natural gas, electricity, water, sewage, and other basic amenities for both residential and commercial consumers. These companies may provide one or all of the above services to their customers.

Usually, firms that deliver these services to the final consumers are mostly subsidiaries of the major corporations going by a variety of business names.

While most companies in the utilities field make a profit, they are typically regulated heavily by public authorities.

Utility companies range from large businesses providing a spectrum of services to specialized, niche companies focusing on wind energy and other services.

In addition to the basic utility services provided, some companies major on energy efficiency alternatives, such as renewable energy like solar panels and wind turbines.

Furthermore, as the world continues to embrace cleaner energy sources and a greener planet, many traditional utility companies are now diving into these areas of renewable energy.

How to Write an ATS-Friendly Resume That’ll Improve Your Chances of Landing Interviews with Public Utility Companies

As technology continues to evolve in the public utilities sector, this changes the way we do everything, and that includes applying for jobs in this field.

For this reason, you need to have an ATS-friendly resume if you want to stay competitive in today’s job market.

ATS resume writing provides enhanced chances for your resume to be seen by potential employers.

They’re optimized incorporating several criteria from layout and design to keywords for ranking high in ATS.

The acronym ATS stands for application tracking system. This is a software program that saves employers time and money by automating the tracking, assessment, and selection of job applicants. 

Data by Forbes reported up to 75% of submitted resumes never get into the hands of an actual recruiter!

This is simply because many of these resumes aren’t well formatted or do not include relevant industry keywords enough to pass the application tracking AI.

Without further ado, below are tips you can incorporate to craft an ATS-friendly resume that’ll land you interviews 3x faster in the Public Utilities sector.

1. Identify the job title and insert into your resume headline

With a well-tailored headline, when a recruiter searches for that job title, your resume will be one of those that shows up! 

Your resume headline is usually found at the top of your resume, just below your name and contact information.

Inserting a headline calls attention to your value as a job candidate.

Proven headline examples include:

“Results-Oriented Business Analyst with 7 Years of Experience”

“Finance Manager with 10 Years of Experience in the Banking Industry” 

“Human Resources Professional with 5 Years of Experience in Recruitment and Employee Relations”

Considering the simplicity of this step, it does not mean that every resume you tailor must have a headline to the job you’re applying to. It’s however, worth it!

2. Identify relevant skills in the job description and add them to your resume

Hiring managers type in specific keywords relating to skills. They do not just type in job titles when they search for applicants.

So, you’d better identify those skills relevant to the job from the job description and highlight on your resume.

Never overstuff your resume with keywords! Doing this practice makes your resume difficult to read and comprehend.

Always ensure to use keywords as naturally as possible. Find out skills to put on a resume.

3. Use keywords properly so the ATS can read them

Since the ATS software can’t differentiate between similar skills, it will be in your best interest to use keywords exactly as they appear in the job description.

Take for instance, a job description requiring “leadership experience,” it would be best to include the keyword phrase “leadership experience” on your resume instead of simply listing your leadership roles. 

Also, it’s essential to include both long-form versions of keywords and acronym versions.

For example, if you have experience working in the Human Resources Management department, you should include both “human resources management” and “HRM.”

When you include both versions of keywords, you’ll offer yourself the best chance of getting your resume noticed.

4. Select an ATS-friendly resume format

Having understood the importance of including keywords on your resume to pass the ATS scan, we’ll advance into selecting the right resume format that passes the ATS scan.

Many qualified candidates craft and submit resumes that can’t be read by an ATS which leads to their resume being rejected despite their great qualifications for the role.

Fortunately, the most commonly used resume format is the most ATS-friendly- the chronological resume format.

The chronological resume format lists your professional experience in a reverse-chronological order. This means your last work experience appears first.

5. Make your resume easy to scan

To ensure your resume is easy to scan, consider the following tips below:

  • Use simple, clear language to make it easy for both ATS and humans to easily understand your data
  • Use a common font like Calibri, Times New Roman, Arial, or Helvetica to appear professional
  • Use font sizes of 11-12 pt for regular text, and 14-16 pt for section titles
  • Ensure margins are about 1 inch on all sides of your resume to avoid cluttering
  • Dates should be formatted in one of two ways: MM/YYYY or “March 2022”. Avoid using only the year
  • Stick to the standard bullet circle or square
  • Use a Word document or PDF so the ATS can easily scan it
  • Proofread your resume more than once as a single error can result in absolute rejection

6. AVOID the following when formatting your resume

Doing the following can confuse the ATS bots and hinder your chances of landing an interview:

  • Using tables and columns while formatting your resume
  • Using headers and footers
  • Using excessive special graphics, images, or symbols on your resume
  • Being too creative or fancy when crafting section headings. Use traditional headings such as “work experience” and “education” to not confuse the bots
