I recently had the opportunity to interview with BrowserStack on campus, and it was a great learning experience. The interview process was well-structured, consisting of four main rounds that tested various aspects of my technical and behavioral skills. Here’s my BrowserStack Interview Experience:
Note: Browserstack focuses on more of Development rather than DSA. So, be well prepared.
1. Online Assessment (3 Questions)
The first round of BrowserStack OA questions had 3 questions about Data Structures and Algorithms (DSA). The questions were of medium difficulty, similar to those found on platforms like LeetCode.
The questions primarily focused on:
- Arrays & Hashmap: basic design class & object of oops.
- Linked Lists: Segregate 0s and 1s.
- Dynamic Programming: basic take and not take algorithm with modified condition.
I was given a fixed time limit for the entire assessment, and I was expected to solve each question within that time frame. It was a great warm-up for the interview, as it helped me refresh my DSA concepts and think through problem-solving in a timed environment.
2. Machine Coding Round (2 hours)
The second round was a machine coding round, where I was given 2 hours to solve a problem. The task involved writing code to implement a feature that could potentially be used in a real-world application. We were allowed to use a browser as well, which helped in searching for any necessary libraries or frameworks.
The key skills tested here were:
- Code Quality
- Efficiency
- Problem-solving
Note: The Question here is repeated often. You can expect one of these questions:
i) Implement log watcher solution (similar to the tail -f command in UNIX)
Java Solution: Link
Web Dev solution: Link
ii) Implement a web service that allows one to interact with two browsers, viz. Google Chrome & Firefox
Java Solution: Link
Web dev solution: Link
During this round, I made sure to focus on writing clean, maintainable code while optimizing for both time and space complexity. This round tested my practical coding abilities and how well I could structure a solution to a complex problem under time pressure.
3. Engineering Manager Round
The third round was with an Engineering Manager. This round was more about my past experiences and how well I understood computer science fundamentals. They asked in-depth questions about:
- Internship Experience: I was asked to explain my internship projects in detail, what challenges I faced, and how I overcame them.
- Computer Science Fundamentals: I was asked core concepts such as operating systems, OOP, networking, and database management systems.
Note: Communication skills are very important at this round.
The interviewer was keen to see how well I could communicate technical concepts and whether I had a solid understanding of the underlying principles of computer science.
4. Director Round
The final round was with the Director, and this one was a bit more casual. The discussion was less technical and focused more on my personality and how I would fit into the company culture. Some of the questions I was asked include:
- Discussing My Resume: This was my chance to walk the interviewer through my professional journey, elaborating on my most impactful projects and experiences that align with the role I was applying for.
- Weekend Activities: Here, they were interested in knowing how I unwind and balance my professional life with personal time, probing into my hobbies and how I spend my free time.
- Code for Production: I was asked to identify the key factors I consider when preparing code for production. This question tested my understanding of production-grade software development, focusing on reliability, scalability, and optimization.
- Behavioral Scenarios: In this part of the interview, I faced situational questions designed to assess my ability to stay composed under pressure, work effectively in teams, and approach problem-solving in practical, real-world contexts.
Bonus Points: BrowserStack Interview Experience
i) Brush up on your computer fundamentals from basics to advanced.
ii) Give a mock interview, which will build your confidence.
iii) Most people are disqualified at the OA and Machine Coding Round, so be well-prepared. I’ve already attached the solution.
If you want to ask any questions, dm: basenect@gmail.com
iii) BrowserStack SDET experience is almost the same as BrowserStack SDE interview experience.
