  • Quantifying achievements like "spearheaded a formidable team of investigators" and "curbed financial losses by a striking 22%" provides concrete evidence of the applicant's capabilities and impact in previous positions.
  • Demonstrating leadership by referencing the ability to "lead a team towards the successful application of strategic, high-stake initiatives" shows readiness for roles that require managing others and overseeing complex projects.
  • Expressing a clear understanding of the company's values, such as "integrity and excellence," and the desire to contribute to those, helps to align the candidate with the company culture and goals.

Key qualities recruiters search for in a candidate’s cover letter

What matters most when tailoring your investigator cover letter salutation

Your investigator cover letter greeting should feel welcoming to recruiters.

Use their first name (e.g. "Dear Marshall" or "Dear Sara"), if you've previously been in touch with the hiring manager and are on a more friendly basis.

If this is the first time you're contacting the recruiters, start your investigator cover letter with:

  • their last name (e.g. "Dear Ms. Ali" or "Dear Mr. Stevens") - look up who's the hiring manager for the role on social media or the company website;
  • generalized greeting (e.g. "Dear HR Team") - just don't use "To whom it may concern" or "Dear Sir/Madam".

Your investigator cover letter intro: showing your interest in the role

On to the actual content of your investigator cover letter and the introductory paragraph.

The intro should be no more than two sentences long and presents you in the best light possible.

Use your investigator cover letter introduction to prove exactly what interests you in the role or organization. Is it the:

  • Company culture;
  • Growth opportunities;
  • Projects and awards the team worked on/won in the past year;
  • Specific technologies the department uses.

When writing your investigator cover letter intro, be precise and sound enthusiastic about the role.

Your introduction should hint to recruiters that you're excited about the opportunity and that you possess an array of soft skills, e.g. motivation, determination, work ethic, etc.

Intro Paragraph
I am writing to express my keen interest in joining your distinguished investigative team at Veritas Investigations, a firm renowned for its innovative approach to solving complex cases and commitment to integrity, which resonate deeply with my professional values and investigative rigor.

What to write in the body of your investigator cover letter

Now that you've got your intro covered, here comes the heart and soul of your investigator cover letter.

It's time to write the middle or body paragraphs. This is the space where you talk about your relevant talent in terms of hard skills (or technologies) and soft (or people and communication) skills.

Keep in mind that the cover letter has a different purpose from your investigator resume.

Yes, you still have to be able to show recruiters what makes your experience unique (and applicable) to the role.

But, instead of just listing skills, aim to tell a story of your one, greatest accomplishment.

Select your achievement that:

  • covers job-crucial skills;
  • can be measured with tangible metrics;
  • shows you in the best light.

Use the next three to six paragraphs to detail what this success has taught you, and also to sell your profile.

Body Paragraph
Spearheading a complex embezzlement case, I utilized forensic accounting to unveil discrepancies and meticulously traced fraudulent transactions over two years, leading to the recovery of $500,000 in misappropriated funds. My keen eye for detail and relentless pursuit of evidence demonstrate an investigative acumen that is both thorough and results-oriented.

Two ideas on how to end the final paragraph of your investigator cover letter

Closing your investigator cover letter, you want to leave a memorable impression on recruiters, that you're a responsible professional.

End your cover letter with how you envision your growth, as part of the company. Make realistic promises on what you plan to achieve, potentially, in the next six months to a year.

Before your signature, you could also signal hiring managers that you're available for the next steps. Or, a follow-up call, during which you could further clarify your experience or professional value.

Closing Paragraph
I am eager to bring my expertise to your team and discuss how I can contribute to your organization. Please contact me to arrange an interview at your earliest convenience.

What could you write about in your investigator cover letter when you have no experience

Candidates with zero professional experience often struggle to write their investigator cover letter.

You may lack experience, but your application could still be impressive when you focus on your strengths.

Consider your most relevant talents (and/or one achievement) that align with the role and help you stand out.

Perhaps you spent every summer volunteering at your local dog pound - think of the job-relevant skills this experience taught you.

Sharing your tangible career goals is another good strategy to stand out.

Key takeaways

Turning your investigator cover letter into a success is all about staying authentic to yourself and relevant to the job:

  • Be creative with your investigator cover letter introduction by stating something you enjoy about the company (that is genuine) or about your skill set (to get the recruiters' interested);
  • Use single spacing and have a one-inch margin wrapping all around the content of your investigator cover letter;
  • Select just one past achievement from your career or life to tell a story of how you've obtained job-crucial skills and how they'd be beneficial to the role;
  • The finishing paragraph of your investigator cover letter doesn't necessarily have to be a signature but could be a promise of what you plan to achieve in the role;
  • Instead of focusing on your lack of experience, spotlight your transferable skills, one relevant achievement, and career dreams.
