Despite the recruiter's claims, it seems Immunefi's true aim is to find a full-stack developer with system design expertise who fits within their senior role budget. This was a common tactic during that period of limited hiring. The initial online test, with its focus on specific technologies like Next.js (a very specific, outdated version), TS and Node.js, creates an impersonal experience, filtering out talented candidates who might lack knowledge of specific tools/versions of those tools but possess strong conceptual understanding. This approach highlights a potential immaturity in the company's hiring process, potentially causing them to overlook valuable talent based on minor details.

They sent me a questionnaire with outdated silly React and NextJS questions that don't make sense anymore since +2 years ago with the latest updates of the libraries. I was in disadvantage because of using the latest versions of NextJS and not remembering old stupid things about React that nobody even used when the library worked solely with classes... and they think that this defines the dev technical abilities; such a shame. The test is was little bit long to my taste, and they rejected me without any feedback or score. Awful experience.
