Coding Round

In this round, you'll be working on a real-world problem and solve it together by writing code in a language of your choosing.

1. System Design Question

Given a road crossing, you have to design a Traffic signal control to optimize the flow of the traffic in all direction. It was a subjective round, the problem was loosely defined, as many real life problems, you could come up with any solutions using any technology. They expect you to think like you are creating solution from scratch.

Problem approach

Tip 1 : It is useful to set up a common project boilerplate before the interview in the language and/or a framework of your project. Be ready to run a simple Hello, World! API endpoint with a database connection
Tip 2 : Completing the problem is not a measure of success for us here. 
They emphasize on your approach towards solving the problem, the abstractions you come up with and the quality of the code.

Here's your problem of the day

Solving this problem will increase your chance to get selected in this company
