I am an intern of/in/at [company name]?

I want to say that I am doing my internship in/at [company name].

Please give me some more examples using the word "intern" or "internship". There seem to be differences between e.g. hospital and business places.

Solution 1:

for company you need to use at:

I am doing my internship at Yale-New Haven Children's Hospital in New Haven

Currently, I am doing my internship at the International Institute of Administrative Sciences, in Brussels, for a period of 16 weeks.

I am doing my internship at ESA-ESTEC

I am doing my internship at Loblaw in Toronto

Solution 2:

Merriam-Webster defines intern simply as

an advanced student or graduate usually in a professional field (as medicine or teaching) gaining supervised practical experience (as in a hospital or classroom)

In practice, however, the nature of work performed by interns and internships varies greatly from profession to profession and industry to industry. For example, in fields with very long training periods such as medicine or architecture, an intern is someone with relatively advanced education and responsibilities. In contrast, in general business and government environments, an intern may be an undergraduate or even a high schooler who is there simply to observe a professional work environment, and whose archetypal workday features mornings at the coffee maker and afternoons at the photocopier.

You can broadly compare to intern with to study or to work, as indeed it lies in between them, and use the same prepositions.

I am an intern at ABC, Corp.

I am an intern in database administration

I am interning at ABC, Corp.

I am interning in database administration.

Now, in the aforementioned fields where intern has a special meaning, you may need to provide additional information to avoid confusion. If you were to say

I am an intern at Memorial Hospital

it would be reasonable for an American listener to assume you are a medical doctor in your first year of residency. If, in fact, you are working in the accounting department, you would need to add the context:

I am an intern in the accounting department at Memorial Hospital

I am interning in the accounting department at Memorial Hospital

I am an accounting intern at Memorial Hospital

I have an internship in the accounting department at Memorial Hospital
