What internships do we offer?

Our internships include unique disciplines related to: 

  • Game dev – 2D/3D Art, Tech Art, Gameplay Development, LiveOps, etc. 
  • Classic software development – Quality Assurance, Front End Development, Back End Development, Analytics, Data Science, etc. 
  • Business – Marketing, Social Media, etc. 


Is it only for students?

No! We invite students, recent graduates, and reskilled specialists who have decided to change their career paths and have studied either through non-formal courses or on an individual basis. 

Do we ask for experience?

No! It might be a plus but definitely not a requirement.

What do we expect from applicants?

Motivation, eagerness to learn, good English language skills, and enthusiasm for developing games.

Do I need to provide a cover letter?

It is optional. Also, check the application form first—there might already be some motivational questions. If there aren’t any, your cover letter will most often take the shape of an interview with a recruiter.

When do we hire?

We have two cycles aligned with the academic year—summer and winter. 

For summer, the application period starts in April, with the internships starting in June–July. 

For winter, the application period starts in November–December, with the internships starting in February. 

How long do the internships last?

They usually last 3-6 months, with expectations of ones lasting 4 to 5 months.

How many internships can I apply for?

If you think that you can be a marketing expert, 3D artist, and software engineer all at once, sure, no limit there. But please, have reasoning prepared as to why you applied to each specific internship because you will only get hired for one of them.

Where do we hire?

Our primary locations are Prague (Czech Republic), Vilnius (Lithuania), and Nicosia (Cyprus), Belgrade (Serbia) but we also have opportunities in Berlin (Germany), Guildford (UK), Chicago (USA), and Austin (USA). Note that you should be present and be able to work in the location where you apply.

Can I work remotely?

Depends on the team, but interns are most often expected to attend the office at least a couple of days per week. This is because we believe in chemistry and synergy shared onsite when people work side by side.

When should I expect a reply?

You should get some sort of reply in up to 1-2 weeks after submitting your application. If you did not, check first whether our email did not get lost in your spam. If still nothing, feel free to ping us!

What to expect?

Experienced mentors, supportive colleagues, top-notch training, real projects, community building activities. Oh, and did we mention it is remunerated?!

Can I work flexible hours?

Yes! We are flexible and happy to discuss how many hours per week you would like to work, taking into account your study schedule if needed. Although, we expect interns to be able to devote at least 20 hours per week to the internship.

We also have internships that require full immersion and are designed for 40 hours a week. Read carefully the description of each specific internship.

What does the hiring process look like?

It depends on the internship, but it normally includes a call with the recruiter, a homework task, and an interview with the hiring manager and other team members, if needed.

What happens after the internship?

By the end of the internship, the best-performing interns will get an offer to join Wargaming, so keep on a good job, and we will make sure you keep on growing with us!

Also, note that even if you do not get a job offer after the internship, you can still be part of the community through the Alumni club (link to more info). We constantly keep in touch with our alumni, organize extra knowledge-sharing sessions, and share recent company news and relevant job offers.
