I applied online. The process took 2 weeks. I interviewed at Gamma Networks (New Delhi) in Nov 2020
Interview
Interview Process was pretty smooth. They have 4 tech rounds in total:
1. System Design round - General design round. Just discuss how to scale application, clarify requirements and provide essential service components
2. Object Oriented Design round - This will involve you to actually code the solution.
3. DS/Algo round - General leetcode questions.
4. Coding round - A command line application to be coded in 2 hours.
Interview questions [1]
Question 1
The interviewer asked me NOT to discuss the questions. You can easily prepare from
1. Grokking System Design
2. Gang of Four and SOLID principles
3. Medium Leetcode should be enough
