My Interview Journey at Rippling: A Detailed Account with Code Insights

Interviewing for a role at Rippling was an experience that tested my technical skills, design thinking, and ability to handle complex scenarios under pressure. Here’s a detailed account of the process, including sample code implementations for the coding challenges I faced, and the final outcomes of each round.

1. Screening Technical Round:

The interview process began with a technical screening round that included an introduction to my background followed by a coding challenge.

Problem:
The challenge was to determine whether a series of currency exchanges could be converted into a profitable exchange cycle, essentially checking for arbitrage opportunities. This problem could be visualized as a graph where each currency is a node, and each exchange rate is an edge with a weight.

Solution Approach:
I explained that the problem could be solved using graph traversal algorithms like Depth-First Search (DFS) and Breadth-First Search (BFS). The main goal was to detect a negative cycle in the graph, which would indicate an arbitrage opportunity.
