What I Learned From Screening and Interviewing Front‑End Candidates

As a front‑end engineer with over a year of experience, I took over many front‑end responsibilities after the previous lead left, and the most challenging part was handling recruitment.

Resume screening

We tend to ignore candidates with little experience or internships because the team is small and the tech stack is demanding. I look for project links, personal blogs with original content, and a clear skill tree. Project links reveal the technologies used, code quality, and structure; even if the candidate didn’t write everything, we discuss their understanding.

Training experience is often a negative sign due to superficial teaching, though good training exists. Frequent job‑hopping isn’t inherently bad; the reasons and process matter. Overstating proficiency on a résumé is a red flag, while honest “familiar with” statements are better.

Interview

Interviews bring diverse candidates. I’m relatively young, so some candidates underestimate me. I’ve seen candidates who claim to have built a canvas game from scratch but provide little substance, and others who ask about underlying principles they don’t understand. I focus on core JavaScript and CSS skills, asking about CSS insights and whether they have built their own JS plugins.

Many candidates come from back‑end backgrounds; their back‑end knowledge can be a plus, but most only use Bootstrap, jQuery, or basic Angular features. Lack of solid CSS and JS experience leads to fragile code.

Grounded principles

The former front‑end lead summarized four essential criteria: personality, experience, vision, and fundamentals, in that order of weight.

Personality is the most important factor.

Accumulated experience makes technology robust and gives foresight.

Vision reflects learning enthusiasm and helps in technology choices.

Fundamentals underpin everything else.

The front‑end market is currently strong, attracting many seeking higher salaries, but some lack real skills and may end up in unstable companies that could disappear when the market cools.

Therefore, staying grounded and focusing on solid fundamentals is key.
