Why Junior Engineers Need More Than Certifications to Stand Out in the AI Era

A mentor at CodeYourFuture, a charity offering free tech training to underrepresented groups, argues that the standard advice given to junior developers — build a portfolio, get certified, contribute to open source — has become a baseline rather than a differentiator. The widespread use of AI tools has made it even easier to produce polished CVs and portfolio projects, further eroding the value of these traditional signals. At London Tech Week, hiring leaders from major tech firms consistently cited curiosity, adaptability, and the ability to learn as their top priorities — qualities that standard CVs and interviews struggle to reveal. The author recommends that junior engineers contribute to unfamiliar open source projects and write publicly about genuine confusion and problem-solving processes, rather than polished tutorials. These approaches demonstrate real-world skills — navigating unknown codebases and thinking independently — that AI cannot easily replicate or fake.
