Interview Process

The technical phone screen interview consisted of several parts:

  1. Introduction: The interview started with brief introductions and an overview of the interview process.

  2. System Design Question: I was asked to design a URL shortener service similar to Bitly. I outlined the key components, including database design, API specifications, and methods to handle URL redirection and storage.

  3. Coding Challenge: I was given a problem to demonstrate code refactoring. The task involved taking a piece of code that was functional but poorly optimized and cleaning it up for readability and efficiency. I explained my thought process step by step as I worked through the solution.

  4. Behavioral Questions: The interviewer asked about my previous projects and how I’ve handled conflicts within a team setting.

  5. Wrap Up: The last part of the interview was dedicated to questions about the company culture and my potential fit within the team.

Overall, the interviewer was friendly and supportive, making the experience less stressful.
