Letter of interest vs cover letter

Wondering how a letter of interest is different from a cover letter? These two letters are powerful tools in the job application toolkit, but they have very different goals.  

Letters of interest, also known as a letters of inquiry or prospecting letters, focus on your intentions and why you want to work for the company, whereas cover letters focus on why you’re the best person to hire for the position. Let’s break it down further. 

Cover letters are tailored or adapted to match the specific responsibilities in a job posting and complement a resume of your related experience and qualifications. The goal is to prove that you meet the criteria for the job, and that you’re the ideal candidate for the role. It’s addressed to the recruiter or hiring manager, includes a summary including key qualifications, skills and valuable experiences that can help secure an interview for the job advertised.  

A letter of interest is a short document sharing why you want to work for a specific company, how your skills and background align with the organization, and why you’d be a good fit. If the company you want to join isn’t currently hiring, a letter of interest can help prioritize your application for when they start hiring or compel them to interview you to learn more.

When to use a letter of interest

Letters of interest can help you build relationships with potential employers and grow your personal brand. Here are some ideas about when you can write letters of interest:

  • There are no roles advertised for your ideal job description. 

  • The company is in the early stages and doesn’t have a jobs page yet. 

  • The company is actively hiring through the “hidden job market”. 

  • The company advertised a role, but you missed it and want to indicate interest in future roles. 

  • To follow up on a conversation from a networking event. 

  • To seek an internship or voluntary role to build experience. 

  • To pitch a transition in your career where you wouldn’t be considered for a job based on past experiences. 

  • To proactively inquire about job opportunities from an upcoming project or initiative. 

The business letter approach is a common job application technique for teachers or teacher’s assistants looking for roles, medical professionals seeking residency, interns looking for a position with their dream company, or even managers thinking about the next in their career.

Elements of a letter of interest

Date and contact information

Format your letter as you would format a business letter. Start by writing the date. Next, share your essential contact information, including your email address and contact number. Make sure the email address sounds professional to avoid making the wrong impression on the receiver. You can also provide your LinkedIn profile link, if it is updated.  

Greeting

It's important to find the right contact in the organization if you want your letter of interest to be read. Citing a name creates a personal connection and shows you’ve done your research about the company.

Direct your letter to a specific person such as the head of HR or the head of the department you’re interested in working with. Need help searching up a name? Find the company’s LinkedIn page or give the organization a phone call to request details. If you can’t find a specific name, you can confidently fall back on “Dear Hiring Manager” as it still makes a professional impression. 

We recommend avoiding generic greetings like “To Whom It May Concern” which is a dated salutation and can reduce the impact of your letter.  

Introduction paragraph

Start with a strong opening, and express what draws you to the organization and makes you interested in potential opportunities. You could share how you admire the brand, appreciate the innovation or have a passion for the industry. These are some approaches to showcase that you are genuinely inspired to work with them. You can also briefly introduce your current position or relevant background to set the scene for your enquiry. 

Qualifications and experience paragraph

In this section, backup your enthusiasm by using brief sentences to share the skills and experiences you bring they will benefit from. Focus more on humanizing aspects of your experiences, by sharing a mixture of technical skills as well as people skills. Cultural fit is an increasingly important hiring factor, so sharing how you align with the company mission and have positive traits like being team-oriented and having a growth mindset can elevate your letter.  

Remember to make suggestions about what you can do for the organization carefully, acknowledging that you are assuming their needs.

Call-to-action paragraph

Close your letter of interest by thanking the reader for their time and expressing your enthusiasm to get in touch soon. You can request to connect over a coffee meeting or virtual meeting through Microsoft Teams to discuss further. Sharing availability such as a few dates and times that suit you in the next week can reduce the hurdle of scheduling, in case the reader is interested.  To close, compliment the organization once again and thank the reader for their consideration.
