Full-Time Role Hiring Process:

In order to grab a full-time offer from Red Hat, I had to go through 4 different tasks which were related to my profile, that is, SRE (Site Reliability Engineer).

1. Project Development: Developing a CLI tool that will integrate the use of Pager Duty and will allow a person to acknowledge alerts, see schedules, etc via a single CLI tool. The project was built in Google Go language which was completely new to me. The project went through extensive PR reviews and made us learn various SE practices like API mocking, T-View, CLI, UI tool, etc. This was a team project consisting of me and another intern.

2. Project Presentation:  After the completion of the project, we had to deliver a complete presentation and demo of the project across various teams i.e 3 teams: NASA, APAC, EMEA (based on region)

3. Toil Reduction ticket resolution: I had to work on a toil reduction ticket and provide a proper solution and analysis with justification to mark the ticket as resolved on JIRA.

4. Oncall duties: This involved being secondary on-call (handling JIRA tickets that are part of SRE support), primary on-call (handling alerts in PagerDuty).

After the completion of my internship, I was offered a full-time role at Red Hat as an Associate Site Reliability Engineer.

The overall experience at Red Hat:

Red Hat is a great organization and I am completely in awe of it. People here are not judged on how much they know, but on their willingness to learn. Red Hat believes there is no such thing as perfection in knowledge and no such thing as the age of learning, even if you are with Red Hat for 6 years, you still are given space to ask and learn. The management is transparent across levels and a plethora of brightest minds here make you enjoy your work a lot, knowing that you are growing both as a person and as a professional.
