The interview was divided into two parts: Part 1 – JavaScript & OOP Fundamentals (≈25 mins): I was asked technical questions on OOP concepts (polymorphism, inheritance, encapsulation, abstraction) JavaScript fundamentals (event loop, event delegation, functions) Web performance/optimization basics Small JavaScript snippet — predict output and correct/improve it Part 2 – JavaScript Coding (≈25 mins): One JavaScript coding problem, followed by ~5 minutes for my questions. I passed this round and moved to the onsite/loop stage. Loop Interviews (4 rounds) 1️⃣ DSA Round: Solved four data-structure/algorithm problems. 2️⃣ Math Round: This round focused entirely on math word problems and formulas. The interviewer expected knowledge of formulas and derivations. I struggled in this round and found the interviewer’s communication style quite discouraging and very very rude. 3️⃣ Technical Lead – Project Deep Dive: Detailed discussion of one past project: Problem context and goals Functional & non-functional requirements Architecture and trade-offs Optimizations Challenges faced What I would do differently if I had to start over Whiteboarding was allowed by a feature in zoom. 4️⃣ Frontend Coding: Implemented calculator functionality in JavaScript based on a provided problem statement. HTML/CSS were prebuilt. Outcome I performed strongly in every round — my technical solutions passed all test cases, were well-optimized, and followed good naming conventions and coding practices. I also discussed ways to further improve maintainability. The technical lead discussion went extremely well, and the feedback during the conversation was very positive. The only round where I felt slightly less confident was the math round. After approximately 1.5 months in the process, I received an automated rejection email with no detailed feedback. I assume the math round may have influenced the decision, although it was not entirely clear how it related to a frontend-focused role. Best of luck to future candidates.
