First, a standard HR interview was conducted on Google Hangouts.

Following that, I received an email with preparations for the next interview. It outlined the following:

• Prepare a presentation of a project I had worked on.
• Practice a few coding tests on HackerRank.
• Read the book "Cracking the Coding Interview."

I completed these tasks and proceeded to the second interview.

During the second interview, they seemed less interested in my project and more focused on my DevOps experience. They stated they are looking for developers with extensive DevOps experience.

I was given a coding assignment to solve on the board, followed by questions on how to scale it. After that, they asked some trivia questions. Although I believed my answers were correct, the follow-up email indicated that I hadn't been precise enough. Therefore, ensure your answers are very clear.

Also, be sure to mention all of your DevOps experience.

I was somewhat disappointed that they were not more interested in my system development skills.
