I interviewed for a Dublin-based position. The interview process had multiple steps:

• Initial interview
• Coding challenge
• Final round (4 interviews, each 45 minutes)

The final round interviews were medium hard.

The first was about system design: Design an endpoint for a form to collect customer feedback to a current Microsoft website.

In the other three interviews, I was asked about how I work in a team, challenges that I have faced in the past, and how I resolved them. Then, each engineer (the interviewer) asked one LeetCode-like question, and I had to walk them through how to code it.

Q: Given an integer, return a string of the formatted integer. For example, given 12348, return "12,348" as a string.

Q: Given a string, return the first non-repeating character in the string.
