Why do you need a thank you letter for an internship

Writing a thank you letter for an internship may seem like an unnecessary task, especially when you’ve already given your time and energy to the company.

However, taking the time to show gratitude and appreciation can have a significant impact on your professional relationships and future career prospects.

Here are some of the reasons why writing a thank you letter for an internship is important:

Shows appreciation

Employers appreciate hearing that their investment in you was worthwhile and that you enjoyed your experience.

It’s a simple way to acknowledge their efforts and show that you value the opportunity they provided you.

Builds professional relationships

Sending a thank you letter can help you maintain a positive relationship with your former employer

This could be useful if you want to return to the company as an employee in the future, or if you want to ask for a reference or recommendation.

It’s a way of keeping the lines of communication open and showing that you’re committed to building a professional relationship.

Leaves a lasting impression

In a competitive job market, it’s important to stand out from other candidates.

A well-written thank you letter can leave a lasting impression on your employer, and potentially even influence their decision when it comes to hiring for future positions.

It shows that you’re a proactive and courteous individual, which are valuable qualities in any employee.

Now that we know the importance of a thank you letter for an internship, you might be wondering when is the best time to send one.


The answer is pretty simple – as soon as possible!

You don’t want to wait too long after your internship has ended because the longer you wait, the easier it is for you to forget the little details and specific experiences that you want to highlight in your letter.

I recommend sending your thank you letter within a week after completing your internship.

This will give you enough time to reflect on your experiences and put together a thoughtful message, while still being fresh in the mind of your employer.

Also, it shows that you’re proactive, and organized, and appreciate the opportunity given to you.
