BrowserStack (Mumbai) Interview Experience – Software Engineer

Last Updated : 21 Oct, 2024

At the time of the BrowserStack interviews, I was having 1.3 Years of experience as an Application Developer.

Round 1: HR Screening Round

Current Project + Previous Project Discussion
Work Experience
Technology Stack

After this, I was called onsite directly. (Generally, they take one skype round before calling onsite)

Round 2: Machine Coding Round – I

Implement the following 4 WebServices in the choice of your language.

startBrowser() -> Start the browser(User Input) and opens given URL(User Input)
stopBrowser()-> Kill the specified opened browser.
getLatestURL()-> Fetched last visited URL (Doesn’t matter browser is running or it’s closed)
deleteAllHistory()-> Delete all the data -> Browser History, cookies, cache, saved passwords, bookmarks etc.

For the last 2, you’ll have to find how does any browser stores user-specific data locally. For Mozilla Firefox, it maintains places.SQLite, (And many similar files)So you’ll have to use JDBC Driver to extract/delete data from .sqlite files of Selenium or any 3rd party automation tool is strictly prohibited.

Round 3: Machine Coding Round – II

Implement functionality similar to tail -f to fetch the latest logs from the given server and send it to all the clients.

Subtask 1:
- For the first part, we were not allowed to use tail command directly by creating a process from code.
- We will have to implement tail -f command programmatically, in such a way that whenever the file is saved, only last changed data is getting displayed
- One more criteria, in almost all languages, default file readers start from line 0, which is also not helpful in our case. As the files might go to some TBs.
Subtask 2:
- Once we have n lines ready, WebSockets can be used, to send the data to all the clients.

Round 4: Hiring Manager Round

Current Project Architecture.
Current Framework Architecture. Core Java -> JSP-Servlets -> JSF-Managed Beans-> Oracle ADF (Similar case for DB-ORM Side was also discussed)
Any one feature you would like to discuss which interest you the most from current work-ex.
Conflict with your manager. How did you handle it?
What did you learn from 1.5 years of professional life, since this is your first company.
Some Questions on Java Frameworks
One question which was based on Map-Reduce Framework. (Discussion on How to modify also so that it can run on Multi-Clustered Environment)

Round 5: Founder Round

Tell me about yourself.
What one thing did you enjoyed the most in the college?
StartUps vs MNC, which one do you prefer, why?
Strength and Weakness
Why you didn’t apply for GSoC?
Why you want to leave your previous organization?

After this, they informed me, they are done for the day. In my overall experience, the interviewers were very friendly and helpful. After 2 days, the HR call was scheduled.
