Interview Experience 🚀 I applied through a referral and soon got a call from the HR team to discuss the role and expectations. This was followed by an initial screening call with the hiring manager. After that, there were 4 technical rounds and 2 fitment rounds, in the following order: --- 💡 Round 1 – JavaScript & Web Fundamentals This one focused on JS output-based questions and how JavaScript actually runs in the browser. Topics included function polyfills, accessibility, web security, and memory management. 👉 Tip: Brush up on how the event loop works, how JS handles async tasks, and common web app performance pitfalls. --- 🧠 Round 2 – Data Structures & Algorithms (DSA) For frontend folks, this round is manageable, but backend candidates might find it a bit tougher. Expect medium to hard-level questions. Key areas: dynamic programming, backtracking, arrays, strings, and problem-solving under pressure. --- ⚛️ Round 3 – React (LLD) A hands-on coding round where I had to build a small React app (the setup was already provided). The interviewer mainly observed how I approached the problem, used React effectively, and wrote clean, scalable code. 💭 Also, stay updated with React’s changelogs and ecosystem—it really shows when you understand "why" something changed, not just "what" changed. --- 🕸️ Round 4 – High-Level Design (HLD) This round was about core web architecture: memory management, state management, authentication, networking, deployments, and security. My advice? Watch a few YouTube videos on frontend system design and learn how to present your approach in a structured way—it helps a lot! --- 👥 Round 5 & 6 – Fitment Rounds These were two back-to-back in-office discussions with senior leadership. They focused on my past work, what I could bring to the team, and what I was looking for from the role. Both were genuinely insightful and conversational—no trick questions here! --- ✨ Overall Experience The interview process at Harness was incredibly smooth and well-organized. All the interviewers were polite, patient, and genuinely curious about my thought process. About a week later, I got the call — I had cleared all rounds, and they’d be rolling out the offer soon. 🎉 --- 💬 Final Tips * Be confident and calm — clarity of thought matters more than speed. * Remember, interviewers aren’t trying to prove you wrong; they’re trying to understand *how* you think. * Think out loud. Involve the interviewer in your reasoning and decision-making. * Treat it like a collaborative problem-solving session, not an exam. Hope this helps anyone preparing! Best of luck 💪

1. First round was DSA - leetcode medium question was asked 2. Second round was React - It was mostly easy 3. HLD round which kept on postponing because interviewers cancelled an hour before everytime 4. Technical Hiring Manager round - This round was in-office round where my previous projects were discussed and the level of complexities handled I was rejected because my background (my current company) is not good enough for them. Felt like a waste of time as this could have been avoided at the resume screening process itself
