I applied online and received the phone screen interview request after a month.

The position is Systems and Performance Engineer, requiring AWS and Azure skills.

The phone interview was based on my resume, projects, basic cloud computing knowledge, and specific AWS questions. The interview went well, and the interviewer was very quick to respond. I received the onsite interview call within 20 minutes of completing the phone interview.

Onsite: There were four interviewers, each with a 30-minute slot. They asked me questions about my resume, scenario-based non-technical questions, two programming questions, AWS questions, and Linux commands.

The question difficulty was average.

They were quick in providing an offer. I received an offer within a day of my onsite interview. At that time, they had an urgent requirement to hire for their cloud project.
