System Design

I went through two rounds of interviews, but honestly, the recruiter didn't seem to be taking it that seriously. After finishing the second round, I haven't heard anything back or gotten any feedback at all. It's been pretty disappointing and feels unprofessional with this lack of communication.

Technical Coding System Design

The interview started with questions about my project, which was on REST. We discussed typical REST questions like why and how to use it. Then, I was asked to design a REST API for a part of my project. A significant part involved designing an Uber Cab service, specifically handling a scenario with 5 lakh drivers sending requests concurrently. I explained how to manage this efficiently using concepts like Load Balancers, Sharding, and Master-Slave configurations, which seemed to be well-received. Finally, I had to write code from front-end to back-end for a driver's location update request using technologies like JavaScript, Ajax, JSON, jQuery, Servlets, and MySQL. I wrote about 2 pages of code, and the interviewer was satisfied.
