We use AI tools to support certain parts of our hiring process, and we believe in being transparent about how they’re used.

During your application, AI may assist in reviewing CVs, qualifications, and assignments by providing additional insights, but it does not make decisions, every application is evaluated at each step by a member of our hiring team.

We also use AI to transcribe interviews so our team can stay focused on the conversation rather than note-taking. Any voice recordings are automatically deleted within 15 days.

In addition, AI helps us keep candidates informed about their application status and helps us understand how our process is working so we can improve it over time.

In all cases, AI is used to support efficiency and consistency, not to replace human judgment.
