Software Developer, Chaos

“The most impactful takeaway from Chaos Camp was learning how to translate theoretical knowledge into a robust, real-world project. The instructors were fantastic at guiding us to build code that's not just functional but also futureproof and scalable. The camp allowed participants to develop a project that demonstrated their skills and helped me land a job at Chaos. While I really enjoyed working on the projects, connecting with other passionate people was a highlight. I’d highly recommend it to anyone with a programming foundation who's eager to dive into Ray Tracing and Computer Graphics.”

FAQ

Who is Chaos Camp for?

Chaos Camp is open to applicants aged 18+ based in Bulgaria, Czechia, or Germany. Applicants must be junior developers, recent graduates, or university students close to graduating in a relevant field such as software development or computer science. Applicants are expected to have knowledge and interest in mathematics, algorithms, C++ development, and coding for computer graphics which will be assessed through the Chaos Camp entry test.

Is Chaos Camp suitable for high school graduates and junior students?

The Chaos Camp 2025 training requires some knowledge and experience in mathematics, algorithms, and C++ programming. If you are aged 18+ and consider yourself well-prepared in these subjects, don’t hesitate to apply. If you are invited to take the Chaos Camp entry test but your results turn out to be insufficient, don’t hesitate to try again next year.

What is the Chaos Camp 2025 admission procedure?

You can submit your application by April 30, 2025. The shortlisted candidates will be invited to take an online entry test to assess their knowledge of mathematics, algorithms, and software development. The approved candidates will join the Chaos Camp intensive training starting May 20, 2025.

What are my chances of admission?

The shortlisted candidates must complete the Chaos Camp online entry test to assess their knowledge of mathematics, algorithms, and software development. Up to 30 best performers will be invited to join the Chaos Camp 2025 course. So you’d better take your time to prepare well for the entry test.
