Summary

I interviewed for a Group SDE-2 role at DP World, which involved a Hackerrank test, a coding round with two LeetCode problems, and a low-level design round. Unfortunately, I was rejected.

Full Experience

R1: Hackerrank Test (90 minutes)

R2: Coding Round

R3: Low level Design

You are tasked with designing and implementing a ride-sharing application where passengers can request rides, and drivers can be matched to them based on proximity. The application should handle different types of vehicles (such as cars, bikes, luxury cars) and support multiple fare calculation strategies. The system must notify both passengers and drivers about ride statuses and calculate the fare based on the type of ride and distance traveled
