FixThis interview questions

1. Initial Screening The process began with a brief HR screening call. During this 20-minute conversation, I shared my background, walked through my experience, and discussed my motivation for joining FixThis. They were particularly interested in my work on projects involving real-time systems and high-performance backends. 2. Technical Assessment Next, I was given an online technical challenge designed to evaluate my full-stack skills. The problem focused on building a mini-application that simulated FixThis's core functionality. It required implementing: A responsive Flutter front end for user interaction. A Node.js/Express.js backend with well-structured REST APIs. Integration with MongoDB for data storage and Firebase for real-time notifications. The challenge emphasized code quality, scalability, and performance optimization. 3. Technical Interview After clearing the technical assessment, I was invited to a live technical interview with two senior engineers. The discussion included: Code walkthrough: They asked me to explain the architecture and design choices in the technical challenge. Problem-solving: I solved a new coding problem live, focusing on efficient algorithms and clean code. System design: I was asked to design a scalable system for handling 10,000+ API requests per minute, reflecting FixThis's user base. 4. Cultural Fit Interview The final round was a behavioral and cultural fit interview with the CTO. This session focused on my approach to teamwork, communication, and problem-solving under tight deadlines. They asked about my experience leading projects and collaborating with cross-functional teams, particularly on platforms with real-time features and high data processing demands.
