This problem requires you to implement a log-watching solution similar to the tail -f command in UNIX. In this case, the log file is hosted on a remote machine (the same machine where your server code runs). The log file is append-only.

You are required to implement the following:

• A server-side program to monitor the given log file and stream updates as they occur. This program will run on the same machine as the log file. You may implement the server in any programming language.
• A web-based client (accessible via a URL such as http://localhost/log) that displays updates from the file in real time, without requiring a page refresh. The page should load once and continue updating as new log entries are added. When a user first lands on the page, they should see the last 10 lines of the file.

Problem Constraints:

• The server should push updates to clients to achieve near real-time behavior.
• The log file may be several GB in size, so you must optimize how the last 10 lines are retrieved.
• The server should not retransmit the entire file each time; it should send only incremental updates.
• The server should be able to handle multiple clients simultaneously.

Most of the questions were based on my resume and the projects I had worked on.

Behavioural questions related to my previous internship experience, as well as questions about my college.
