Technical Coding Behavioral
The interview started with a technical online assessment, mostly easy MCQs. After that, I had to build a server-side API prototype. For me, it was implementing 'tail -f' via sockets to get real-time log file updates. I had 2 hours, no AI help but could google simple things. My advice: don't use AI to build everything; do your homework on web dev, networks, and Web Sockets. They likely don't expect a full production frontend and backend. Just build what's asked honestly and clearly. Walk through your logic and code, talk a lot. I did this, communicating even without a frontend, just a bare-minimum backend, and got shortlisted. The final round was an interview, either alone or with a partner, where I was unfortunately rejected. Tip for the final round: explain/show your projects and resume; do your homework properly.

Behavioral Technical Coding
A recruiter hit me up on LinkedIn and told me about the company. They asked what salary I was expecting and then set up the first round, which was also the elimination round. The interviewer wasn't very friendly.

Technical Coding Behavioral
I went through the BrowserStack Catapult on-campus placement drive for a Software Engineer - Backend role, which is a placement-linked internship. First, I had an Online Assessment with MCQs covering Web (HTML, CSS, JS), OS, CN, and situational questions, ranging from basic to medium difficulty. After clearing that, I was invited on-site for the next stages. The second round was a Machine Coding round at their office, where the task was to build a classic tail -f like log streamer using web sockets. I successfully passed this round too. The final round was an interview with the Director of Engineering. This interview focused heavily on my resume, asking about my internship experiences, projects, strengths, and weaknesses. It was a mix of technical and behavioral questions. The results were announced by the placement cell a week later, and I got selected!
Confirmed questions3 questions
- In a scenario where a project deadline is a week away and significant work remains, how would you manage it as a team lead?
- Given a service failure reported by your project lead with accompanying server logs, what steps would you take to resolve it while ensuring minimal downtime?
- Can you describe some of the challenges you've faced in your recent projects and detail how you solved them?
BrowserStack Software Engineer Interview Questions
Quoted word for word from BrowserStack interview reports.
“Given a log file with comma-separated values (Process ID, timestamp, and event like start/end), print all processes whose execution time is greater than 3 (end time minus start time), assuming Process IDs are unique.”
Read reports →“Implement a server-side program that monitors a given log file on a remote machine and streams real-time updates, functioning like the tail -f command.”
Read reports →“How would you sort an array of size N containing elements from 0 to N-1 without duplicates in O(N) time?”
Read reports →“Could you write a websockets-enabled 'tail -f' server that will not keep files open, but will repeatedly poll the mtime of the file and not return the whole output each time a user connects?”
Read reports →“Could you implement a log watching solution, like the tail -f command, but for a remote log file on the same machine as your server code? The log file is in append-only mode.”
Read report →“Can you build a web-based client (accessible via a URL like http://localhost/log) that displays updates to the file in real-time, without requiring a page refresh?”
Read report →“Can you build a system that watches log files and streams changes to multiple clients in real-time, like `tail -f`?”
Read report →“Can you build a real-time update page that fetches details from a server log file without needing to reload the page?”
Read report →“Could you sort an array of N elements, where each element is less than N and there are no duplicates?”
