Interview Process

I had my first coding interview with Google recently. It was quite interesting and challenging. The interviewer started with a brief introduction and explained the format of the interview. Then we moved onto the coding questions.

The first problem was related to trees where I had to find the sum of distances in a tree. The interviewer guided me through the process, marking my thought process as I discussed my approach. The second part of the interview focused on behavioral questions, where I talked about my past experiences working in teams and how I approached challenging situations. The interviewer asked follow-up questions that prompted me to think deeply about my answers.

Overall, it was a great experience, though I felt the pressure as it was Google. I am waiting for feedback, but I believe I did my best!

Tips & Insights

Stay calm and articulate your thought process clearly during coding challenges. Be prepared for follow-up questions in behavioral segments that require deeper reflection on your experiences.
