They held a weekend recruitment drive, and I was interviewed for a senior position on one of the big teams.

I went through a total of four rounds:

• Programming/Algorithm
• Design/Programming
• Design/Managerial/Technical
• Directorial/Architectural

All rounds were conducted via Zoom. The entire process was clearly communicated and coordinated.

In each round, I was asked questions on multiple topics, varying from programming, algorithmic design, coding practices, automation, data structures, and SOLID principles.

Once I cleared the interview rounds, I was immediately informed that I was hired.

Coding Round:

Finding if a string is an anagram of another.

If A, B, and C are three non-zero digits (1-9), find all combinations of A, B, C such that AB * AB = CAB.

Find all pairs of consecutive array elements which sum to a given number.

Design Round:

Design a system that returns to a user all restaurants within a 2 km radius of their location. No usage of external APIs is allowed. Only latitude and longitude location details are provided.

Write a program to remove the minimum number of incorrectly formed braces from a string and print it.

Managerial Round:

Write a program that will last the test of time. This means that future requirements might change, but the code should only minimally change.

Director Round:

How would you manage a huge chunk of legacy test cases effectively, making them easy to maintain?
