Experience:

This candidate had 1.3 years of experience as an Application Developer.

Round 1: HR Screening Round

• Discussion on current and previous projects.
• Work experience.
• Technology stack.

Round 2: Machine Coding Round - I

• Implement 4 Web Services: startBrowser() (start browser with URL), stopBrowser() (kill browser), getLatestURL() (fetch last visited URL), deleteAllHistory() (delete browser data like history, cookies, cache, passwords, bookmarks).
• For the last two, the candidate had to figure out how browsers store user-specific data locally (e.g., Mozilla Firefox uses places.SQLite) and use JDBC Driver to extract/delete data. Selenium or any 3rd party automation tool was strictly prohibited.

Round 3: Machine Coding Round - II

• Implement functionality similar to tail -f to fetch latest logs from a given server and send to all clients.
• Subtask 1: Implement tail -f programmatically without using the actual tail command or default file readers that start from line 0, as files could be TBs in size. Only last changed data should be displayed when the file is saved.
• Subtask 2: Use WebSockets to send data to all clients once 'n' lines are ready.

Round 4: Hiring Manager Round

• Discussion on current project architecture and framework architecture.
• Questions on Core Java, JSP-Servlets, JSF-Managed Beans, Oracle ADF.
• Discussion on a feature from current work experience that interested the candidate most.
• Behavioral questions: conflict with manager and how it was handled, learnings from professional life.

Round 5: Founder Round

• "Tell me about yourself."
• "What one thing did you enjoy the most in college?"
• "StartUps vs MNC, which one do you prefer, why?"
• "Why didn't you apply for GSoC?"
• "Why do you want to leave your previous organization?"
• "Why BrowserStack?"
