Frontend Tech Specialisation Mock Interview with Nitesh Sinha

In this round, I'll ask you the kind of frontend questions you can face in real interviews: JavaScript fundamentals, closures, the event loop, promises, React internals, rendering, browser concepts, performance and web security. I'll go deep with follow-ups, just like a real interviewer.

My questions are original, not the usual ones you find online. You can't answer them by memorising, but anyone with a strong understanding of frontend concepts can crack them.

What you'll get:

• A 1:1 real interview experience on core frontend concepts
• Fresh questions that test your understanding, not your memory
• Detailed feedback on your concept clarity and answers
• The topics you're weak in and how to fix them

Why me:

• Senior Frontend Engineer at Zomato with 5+ years shipping JavaScript and React at scale
• In-depth performance optimisation: Core Web Vitals, re-render profiling, memoisation, lazy loading, code-splitting and tree-shaking
• I build reusable packages from scratch, so I know module systems, bundlers, build tooling and clean API design inside out
• I build rapid prototypes, turning rough ideas into working UIs fast, so you get real-world answers, not textbook ones
• Follow-ups at the depth of Google, Flipkart, Uber and Zomato rounds
