In January, a recruiter contacted me for a phone call to describe the role and gauge my interest. Once I confirmed my interest, I advanced to the next stage: a phone screen interview.

This interview involved two coding questions (one Easy and one Medium LeetCode style), followed by several SRE-oriented questions covering networking, Linux, and troubleshooting.

The phone screen was pleasant and relaxed, and the interviewer was very kind.

A few days later, the recruiter contacted me again, informing me I was moving on to the onsite interviews at Microsoft's office in Dublin. This was a full-day event, comprising six interviews:

• Systems Design
• Troubleshooting
• Lunch
• Coding Challenge
• Software Design (very difficult)
• AA

Each interview was intense in difficulty, but the interviewers were polite and helpful in guiding me.

A week later, I was contacted with the offer.

Design a library that developers can use to send metrics to a server.
