BrowserStack - Fullstack Developer

The HR round happened shortly after my referral was shared. The recruiter discussed my educational background, current experience, and the projects I had worked on. We also spoke about my reason for exploring new opportunities, role expectations, and availability. I was informed about the upcoming weekend hiring drive and the overall interview structure.

This was an extensive machine coding round of around 3.5 hours. All candidates initially joined a common meeting and were later assigned individual breakout rooms.

The round consisted of two tasks. The backend task required building a log file reader that could stream real time updates to connected clients using sockets. The focus was on handling live data efficiently.

The frontend task involved implementing a pixel perfect UI from a provided Figma design to display logs received from the backend. Special attention was required for scrolling behavior and UI accuracy.

This round tested real world development skills, and I received positive feedback.

This round was conducted by engineering managers and lasted about 45 minutes. We started with a discussion on my previous projects and technical experience.

I was asked to explain an approach to count the frequency of words in a text file and then extend the solution for very large files ranging from a few megabytes to several gigabytes. The conversation included optimization techniques, concurrency, and multithreading.

Behavioral questions related to teamwork and conflict resolution were also part of this round. Overall, the difficulty level felt moderate.

This round focused on system level thinking and scalability. After introductions, we discussed my previous work and the technologies I had used.

I was asked how I would handle an application that suddenly receives massive traffic overnight. Topics included system stability, monitoring, alerting, scaling strategies, and handling critical failure scenarios. The discussion went well and felt more conversational.
