Round 2 (Technical Round)

This was a pure technical round. The interviewer asked about multiple approaches to one coding problem. It was more like a discussion and the interviewer wanted to judge my thinking process and communication skills.

Then he asked me about my current project roles and responsibilities, then he jumped into microservice architecture since my current project was based on microservice architecture.

• How does microservice architecture promote CI-CD deployment ?
• What is the purpose of the API gateway?
• Authentication and Authorization access in microservices
• Difference between monolithic and microservices
• Difference between relational and non-relational database
• How will you scale the database?

He asked me the coding question related to 3Sum. I gave a brute force approach where a method is used to generate all possible triplets and compare the sum of every triplet with the given value.

However, the interviewer was not happy with O(n³) time complexity and then asked me to optimize the code. Then I solved the same question using a pointer approach with O(n²) time complexity.
