I applied for the SDE-1 Backend role at Juspay through their careers page without much expectation. To my surprise, the HR team called me within days and scheduled the entire process for their Kolkata office. What followed was one of the most intense and mentally exhausting interview loops I’ve ever experienced. Juspay’s process is genuinely different and tests real engineering and problem solving depth. Even though I got rejected, I respect the process a lot.

The current implementation of the queue and storage systems demonstrates a powerful and flexible way to handle asynchronous job dispatching and processing using Go. The use of concurrency ensures that jobs are processed swiftly and reliably while maintaining simplicity in the design. This structure allows for scaling and adding more functionality over time.

GraphQL is a query language for APIs that allows clients to request exactly the data they need, making it highly efficient and flexible. Unlike REST, which requires multiple endpoints for different resources, GraphQL consolidates everything into a single endpoint where clients can specify the structure of the response.

In this blog post, I’ll walk you through the process of migrating a NestJS monorepo application to Kubernetes, using Minikube for local development. The project consists of two monorepo :- control-panel and auth, both of which rely on MongoDB for data storage and Redis for caching. The MongoDB instance is set up with a master-slave architecture using a StatefulSet, while Redis is deployed as a single pod.

Seeders play a crucial role in initializing and populating a MongoDB database with initial data. Whether you’re setting up a new development environment or running tests, having a robust seeder can streamline the process and ensure consistency. In this blog post, we’ll delve into the correct way of creating seeders using MongoDB and Node.js, leveraging the power of the mongodb bulk write feature using initializeOrderedBulkOp() method.
