After screening your resume for the Google engineering manager post, you will undergo the first round: the phone interview. Here you will need to present basic background information, answering why you are fit for the respective post in Google. There will be behavioral and resume-related questions.

• Tell me about yourself.
• Why do you want to join Google?
• Why will you be a good fit for the company?
• Tell me about your current day-to-day as an Engineering Manager

You'll be tested on your knowledge of data structures and algorithms over the phone or via video chat. You will face questions on topics related to graphs, strings, recursion, dynamic programming, geometry, and algebra. Additionally, you will face questions about your work experience and projects you worked on.

• Design a solid system in a graph to view the latest stock prices from the global stock market.
• Design a software system for our photo-sharing website to store and retrieve photos and thumbnails.
• Convert the data into workable code or explain it in the algorithm.

This is the final round of the Google engineering manager's interview process. There will be three divisions in this round-

1) Leadership Interviews

2) The System Design Interviews

3) The Coding & Algorithm Interviews

Leadership Interview-

There will be 2-3 rounds of this interview. Besides technical questions, you will face questions about team leadership and project management. Under this, you will need to discuss your previous experience managing teams, projects, and behavioral inquiries regarding your approach. Questions will be about your approach towards team development and retention, your capacity to lead in complicated, ambiguous, and challenging circumstances, and your capacity to oversee a project from start to finish and deliver. The interviewer will check your ability to face complex situations and manage your team during the project work.

System Design Interview

In this round of interviews, you will need to demonstrate both your creative and organized qualities. However, there are chances that the interviewer may modify the question to fit your background. They might ask you to create an API, for instance, if you've worked on an API product. However, given that this won't always be the case, you should be equipped to develop any system or product at a high level.

The Coding & Algorithm Interviews

Google software engineers work on solving complex coding or systems. During this round of interviews, you will be tested on your skills in sorting, algorithms, math, and data structure. One of the interview tips you can follow is to have experience writing code without an editor to help with syntax. Also, you'll be coding on a whiteboard, so practice writing on paper or a whiteboard.

Leadership Interview Questions-

• Tell me about a time when you faced a technical and interpersonal challenge in your current role.
• Tell me about a time when you worked with a super performer in your team, and how did you handle it?
• What do you do when someone you manage doesn’t deliver as promised?

To answer these questions, you can give examples of previous projects. Present the situation on how you evaluated the success or failure of the project.

System Design Interview Questions-

• How would you design Google Docs?
• How would you design Google Home (voice assistant)?
• How would you design a ticketing platform?
• Design an in-memory cache for webpages

Coding Interview Questions-

• Given a binary tree, find the maximum path sum. The path may start and end at any node in the tree.
• Given an encoded string, return its decoded string.
• Two strings S and T. Task: Find the minimum window in the string S, which will contain all the characters in the string T in complexity O(n).
