Interview Experience – Frontend Engineer I applied via referral and was contacted for an initial recruiter screening. The screening covered my background, work experience, tech stack, and overall fit for the role. After passing this stage, I had a technical recruiter round divided into two parts: Part 1 – Resume Deep Dive / Frontend Fundamentals: The interviewer asked detailed questions about items mentioned on my resume. I had listed frontend performance optimizations (e.g., lazy loading, memoization, etc.), so they asked: How and why I implemented those optimizations When to use specific techniques (e.g., memoization) Additional performance strategies How a web page loads CSR vs SSR concepts The goal was to assess depth of understanding and ownership of my past work. Advice: Be prepared to explain anything on your resume in depth, including fundamentals behind it. Part 2 – DSA Coding: One coding problem (array-based). I discussed the brute-force approach first and then the optimized solution. I completed both sections, but I struggled somewhat in the resume deep-dive discussion and took longer than expected in the coding portion. I later received a rejection. Best of luck to future candidates.
