MMT Interview Experience

Round 1 – Word Search
The problem had multiple variations:

• Check if the word exists in the grid
• Count the number of occurrences
• Print the starting and ending positions of each occurrence

I provided a DP-optimized solution, and the interviewer seemed satisfied.

Round 2 – LLD (RedBus)
I was asked to design RedBus with the following features:

1. Search buses
2. View and manage seats
3. Seat reusability
4. Book tickets
5. Payment integration
6. Fare strategy
7. Notifications

I covered all parts and explained the design, but:

• The interviewer expected UML diagrams, which I couldn’t complete in time
• He wasn’t happy with the time complexity of the search functionality
• After a few resume-based questions interview ended, Got call from recruiter that feedback is not positive.
