What can you expect

Flexible arrangement

The length of internship can last from three to twelve weeks. The exact length, type of work, working hours and payment are discussed fittingly before starting the internship.

Mentor & all necessities

Upon starting the internship you’ll be provided with all necessary equipment and an appropriate wingman, who will work closely with you on your assignments.

Fair pay

As a company we do not work for free, so we don’t expect anyone else to. We compensate for even the shortest internships.

Employment options

It’s no secret that we want to prolong work with all interns who are a good match with our values, people and professional standards. Internship at 3fs is a perfect starting point for working for us long term or, let’s put it this way: a very long hiring interview.

"Internship at 3fs was an educational as well as fun experience and an excellent springboard into the world of software development."
