The interview was easier than I thought it would be.

First Round:

A one-hour-long, healthy discussion. They asked about the current project in detail, from architecture to the technology being used and the release/deployment process. For example, "What sort of storage options are being used? RDBMS vs. NoSQL vs. cache vs. message queue?" They also asked two to three Java/OOPS questions, which were pretty basic.

Second Round:

Core Java standard questions:

• Tree vs. List vs. Set
• OOPS

Docker basics: Write a sample Dockerfile.

Kubernetes: The interviewer was quite knowledgeable in Kubernetes. They asked about Kubernetes architecture and patterns used (Controllers, StatefulSet, Operators, etc.).

Third Round (Managerial):

A one-hour-long discussion with the hiring manager, mostly non-technical, behavioral questions. For example:

• How to react in certain situations.
• Are you following Agile in your current project? Have you worked on scrum teams?

I had no idea about SAP not being a paymaster. I was offered a number that was almost the same as my current CTC, so I had to decline the offer. Other aspects included in the offer were pretty decent, though, like the SAP ESPP policy and higher education policy.
