  • Backend experience with Java and Spring / Spring Boot, confident handling of relational databases, and basic knowledge of REST/web services.
  • Basic knowledge of Git and interest in working with GitLab, Docker, Kubernetes, and CI/CD.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
