The second round of the Google Software Engineer interviews consists of phone screens with software engineers. Technical interviews are 45-60 minute whiteboard-style interviews and test your basic coding skills through 2 questions. You will be required to share your screen and write the code on a Google Doc or similar text editor. Questions will be asked from the following topics -
- Data Structures - topics such as BST, Linked List, Recursion
- Dynamic Programming
- Graph theory
You will be asked follow-up questions about the solutions you have provided for the questions. Additionally, the interviewers will also discuss elements of your resume, especially the projects you have worked on. This is going to be crucial for your selection as Google Software Engineer.
- A very important thing about interviewing for the Software Engineering role at Google - you will have to code on Google Docs or a similar text editor. Therefore, many features such as indentation and syntax auto-complete will not be available. Also, since you will not be able to compile the code, it is recommended that you get enough practice so that you are comfortable during the interview.
- It has been observed that many questions are similar to easy and medium-level LeetCode questions, so practicing them can help you be better prepared for the Google Software Engineering interview.
- Be prepared to answer questions related to the projects as the interviewer may ask about them in great detail, especially if they are relevant to the specific role you’ve applied for. You can be asked to describe how you came about a particular feature or the challenges you faced while programming it.
Google Software Engineering Role Coding Interview Questions -
- Write a code to create a pyramid of numbers.
- Write a code that gives the shortest path search for a given linked list?
- Write a code to check if the given binary trees are identical.
- Write a program to reverse a linked list.
- Write a code to find the longest sequence in a binary tree.
- How to Traverse a Binary Search Tree?
Note - Questions related to traversing 2D matrices, DFS, and backtracking may also be asked.
You may have another technical interview for the Google Software Engineering role if you’re a borderline candidate.

The onsite round of the Google Software Engineer Interview is generally considered the toughest round. In this round, you will have 5 interviews with various executives of the company. Out of these, 4 will be technical interviews that will test your programming skills, and 1 will be the ‘Googlyness’ interview.
1. Technical Interviews - Google Software Engineer
Each technical interview will last for 45-60 minutes. If you have applied for a specific role, such as Machine Learning Software Engineer, then at least one of the rounds will be Machine Learning-centric. Here, we will discuss the general Software Engineer interview flow. The following topics are tested in the technical interviews -
- Data Structures
- Dynamic Programming
- Graph Theory, BFS, DFS
2. Googlyness Round for Google Software Engineer role -
At Google, interviewers are on the constant lookout for people with a purpose and who are eager to make an impact. This round helps the interviewers do this, and assess whether you are a good fit for the company or not.
