I applied online. The process took 1 day. I interviewed at Biz2X (Noida) in Jan 2025
Interview
My interview experience was positive overall. I was able to discuss my experience and skills in depth, particularly with Angular, Node.js, and database management. The interviewer asked about various topics such as lifecycle methods, access modifiers, and ORM, which I answered confidently. We also touched upon practical scenarios, and I explained how I would handle state management and component communication in Angular. However, I struggled a bit with unit testing, as I hadn’t worked extensively on it. Despite this, I felt the interview went well, and I was able to showcase my expertise in most areas.
