I applied through a recruiter. The process took 2 weeks.

Interview begins with recruiter calling, explaining you the process:

• Coding round
• System Design
• Hiring Manager round
• Bar raiser round

Each rounds are qualifier to another round. I did the coding round and system design, and I was ruled out.

Coding round for the Matrix grid problem for 60 min coding round.

First Part of the problem:

• Randomly fills a matrix (a * b) with 5 'x' alphabet, reset would be 'o' alphabet

Second part of the problem (minesweeper game on Windows OS):

• Given a matrix fill with 'x', find number of minds adjacent to it

You need to solve both problems in 40 mins to qualify (First 10 mins Introduction, last 10 minutes is follow-up question). Remember to ask follow-up questions else it mark as candidate isn't proactive in asking questions.

1. System Design Round (90 mins) They ask to design an internal developer portal that establishes a fully automated, version-control CI/CD pipeline at scale. It basically involves designing the Internal developer, I started with requirements, non-functional requirements, entities in system, I started with API design but they said it's okay to skip, and high level design. I started with Component-Based Design where I drawn frontend, CLI, API Gateway, catalog services, ... and all other components of the developer portal.

But they were interested in detailed CI/CD pipeline steps. This is where I screwed up; I caught the hint much later in the interview when there were 10 mins left, and I quickly drawn CI pipeline and a CD pipeline, but wasn't able to explain each step in the CD pipeline in detail. They wanted a more comprehensive Workflow and Operational design of CI/CD pipeline instead of a component-based design of the internal developer portal. Since I didn't complete the design, I was ruled out of the interview.
