What is an expression of interest for an internal job?

An expression of interest (EOI) for an internal job? is a formal message showing your interest in a new role within your current company when an opening hasn’t been advertised. Unlike a cover letter, which responds to a specific job opening, a letter of interest for an internal job focuses on your long-term goals, internal experience, and alignment with the company’s direction.

Why send a letter of interest for an internal position?

Writing a letter of interest for an internal position helps you stay ahead of the curve. It signals your long-term commitment to the company, demonstrates initiative, and may even prompt managers to consider creating a role that aligns with your goals. Whether you’re seeking a promotion, a transfer, or new responsibilities, this kind of internal application allows you to start a conversation before roles are publicly listed.

If you’re not sure whether writing an expression of interest for an internal job is a good idea, keep in mind that it’s not only you who can benefit. According to a report by LinkedIn Learning, employees who are given opportunities to move internally are 3.5 times more likely to be engaged with their work and the company's mission. Additionally, a recent Workday study found that internal hires were 82% more likely to be rated as a "top performer" during their first performance calibration compared to external hires!

How to write an expression of interest letter for an internal job

To write a letter for an internal position, you must know your audience and present yourself as a valuable long-term asset. Here's how to structure your EOI letter, with examples for each step:

1. Start with a clear and professional introduction

Begin your letter by clearly stating your intent to apply for an internal opportunity. Mention your current role, your time at the company, and the type of position you're interested in.

Describe what motivates your interest in the position or department. Focus on how it aligns with your career goals and the company’s direction.

Demonstrate how your current role and past professional accomplishments make you a good fit for the new opportunity. Use concrete examples.

Over the past year, I led a cross-departmental initiative to streamline reporting procedures, which resulted in a 15% increase in team productivity. I’ve also mentored two junior analysts who have since been promoted. These experiences have prepared me to take on broader responsibilities.

4. Emphasise your knowledge of the organisation

Demonstrate your understanding of the company’s values, goals, and challenges. This is one of the main advantages of an internal application.

Letter of interest for an internal job example

Subject: Expression of Interest – Internal Opportunity in Operations

Dear Ms. Eleanor Hughes,

I hope this message finds you well. I am writing to express my interest in exploring new opportunities within Britannia Logistics, particularly in a leadership or project management role in the Operations department. In my current position as Senior Analyst, which I’ve held for over four years, I've consistently sought ways to drive efficiency and foster cross-team collaboration.

My interest in this area stems from the exciting changes underway in Operations and my desire to be more directly involved in shaping our strategic goals. Over the past year, I led a project to automate client reporting workflows, resulting in a 30% reduction in turnaround times and an improvement in client satisfaction scores. This, combined with my experience mentoring junior team members and collaborating across departments, has prepared me to make more meaningful contributions to the team.

I understand the company’s goals regarding scalability and operational efficiency, and I feel confident that my skill set aligns well with these priorities. I’d welcome the chance to discuss how I might support these efforts in a more formal capacity.

Thank you for considering my internal application. I look forward to the opportunity to contribute in new ways.

Sincerely,

Oliver Grant

Senior Analyst

How does a letter of interest differ from a cover letter for an internal position?

It’s easy to confuse a letter of interest with a cover letter, especially when you're already working within the organisation. However, they serve different purposes.

A cover letter for an internal position is typically written in response to a job opening that has been publicly posted. It focuses specifically on why you're an excellent fit for that exact role, often aligning your experience with the job description. Similarly, a cover letter for a promotion highlights your qualifications for a higher-level role that’s been formally announced, typically within your current team or department.

On the other hand, a letter of interest for an internal job is more exploratory in nature. It’s not tied to a listed vacancy. Instead, it signals that you’re open to new roles, interested in contributing in a new way, or looking for career growth. Think of it as a proactive step – a way to start a dialogue about potential internal opportunities before they even arise.

Understanding the difference can help you choose the right approach and better position yourself for advancement.
