Is this considered an internship, job, or any form of employment?

No. The MLH Fellowship is an educational fellowship program. Think about it like taking a class. 

Fellows may receive an educational stipend as part of their participation to help offset living and educational expenses during the course of the program. If you are a United States resident, you may receive a tax document from our payment provider at the end of the tax year.

If you are an international student studying in the United States, you may need to consult your university to make sure you are eligible to go through the program. Many past Fellows had to request CPT and OPT to stay compliant with their school programs.
