Hiring highly qualified individuals from diverse backgrounds is the first step in Google’s hiring team’s goal of creating a more inclusive and representative workplace. Here are the most-often asked Google interview questions and answers for freshers and experienced professionals.
Google Hiring Process
A diverse workforce with equitable recruiting practices is the first step for Google toward building an inclusive workplace. Google hires from entry level to leadership positions across the world. The hiring process at Google is as follows:
Recruiter Connect: If you want to work for Google, you need to create connections over LinkedIn or other equivalent platforms. Search for openings through career searching tools and find your relevant job profile. Then you can apply according to your skills, locations, and experience.
Interview Rounds: Below are the interview rounds at Google:
- Assessments: You can be asked to complete the Google Hiring Assessment before interviews, which is intended to gauge the workstyle competencies necessary for employment at Google.
If appropriate for the position you’re looking for, you might additionally be required to finish other tests, such as a coding exercise.
- Virtual Chats: Then, you will have one or two phone interviews or video talks before moving into more in-depth ones. It would be with the hiring manager or peers on the team.
- Project Work: Before conducting in-depth interviews, Google requires candidates to finish a brief project. This could include writing code examples or perhaps preparing a case study.
- Interviews: The Google interview procedure can be demanding (usually three to four in-person or video interviews in a single day), but it’s also designed to be warm and welcoming and provide you with the chance to learn more about the workplace. It consists of the following:
- Structured interviewing: Using transparent assessment criteria, Google analyzes each candidate using the same standards for all candidates considered for that position. This ensures that each candidate is examined equally and gives their uniqueness the chance to shine through.
- Open-ended questions: The interviewer asks open-ended questions to find out how you approach situations and learn about your thought process, team dynamics, and areas of strength.

1. What is the purpose of TCP protocol congestion control?
Congestion control methods are built into the TCP protocol to either prevent congestion or lessen it once it has happened. TCP uses the congestion window that is kept up to date by the sender, as opposed to the sliding window used in the flow control method.
2. How does the HTTP protocol handle cookies?
A header field is used to transmit a cookie as part of the HTTP protocol. Cookie lifecycle: There aren’t any cookies when a browser connects to a server for the first time. The server generates a special identification and includes it in the response’s Set-Cookie: header.
3. Is there a reason why most of Google’s homepage is blank?
The Google founders made it easier for visitors to navigate after obtrusive pop-ups and ads, which eventually resulted in an improved design.
4. What is A/B testing?
Comparing the effectiveness of two versions of a piece of material to determine which one visitors or viewers prefer is known as A/B testing, also known as split testing or bucket testing.
It compares two versions, such as the control (A) and the variant (B), to determine which is more successful in light of your important performance indicators.
5. How should an unstyled content flash be handled?
Developers can utilize browser add-ons that can dynamically disable a web page’s CSS in order to simulate a burst of unstyled content. Among these add-ons are Firebug and Async CSS. Other methods include manually terminating a page’s CSS component loading process.
6. What is UX’s newest big thing?
Adding artificial intelligence (AI) and machine learning (ML) to the design process is probably the newest big thing in UX design. Based on user choices and behavior, UX designers may leverage AI and ML to build more customized experiences for consumers.
7. In Java, how may duplicate values be eliminated from an array?
An array can have duplicate elements removed in one of two ways: by utilizing a distinct index or a temporary array. The array needs to be sorted in order to remove the duplicate element. You can sort an array by using the Arrays.sort(arr) method if it isn’t already sorted.
8. What distinguishes user experience from information architecture?
- While UX focuses on evoking an emotional response in the target audience, IA concentrates on navigation.
- UX enhances a user’s natural behavior by providing context and narrative. Whereas UX concentrates on enhancing usability, IA aims to provide a usable experience.
9. What is multithreaded programming?
An executable program with several threads of execution, each operating on a separate processor, is called a multithreaded program. On several processing cores, multiple threads may occasionally run concurrently.

11. Write the algorithm to find the sum of two linked lists using stacks.
Approach: There are two numbers that require addition that are shown as stacks. Each of the two stacks, “A” and “B,” contains “N” components. Our goal is to find the total of those “N” elements, each represented as a large number.
The total of the numbers should not exceed 10. The carry of the sum must be taken and added in the subsequent addition operation if it is 10 or greater.
Example:
Stack1: [3,8,1,3,5]
Stack2: [6,2,4,3,5]
38135 + 62435 = 100570
Algorithm:
- Set up two stacks to hold the two numbers.
- Take the uppermost component out of both stacks and add it using carry.
- Place the total inside the stack.
- After the top elements have been taken, store the carry and remove it.
- We must add carry to the total if it occurs at any stage.
- Proceed to the next piece at the top after making sure the initial stack is not empty. Verify the second stack in the same way.
- Compute the total and add it to the stack of answers. Continue doing this until the stack is empty.
- Give the answer stack back.
- Print the components from the stack of answers.
12. In the event that someone is unfamiliar with accounting principles, how would you describe the balance sheet?
A balance sheet is a straightforward financial statement that lists your assets and liabilities on one page. They are easy to understand and make.
- It lists the assets owned by your firm on one side and your debt and ownership stake in the business on the other.
- A balance sheet will provide a quick summary of your company’s current financial situation to you, your lenders, and your investors.
- That is, a balance sheet is your thermometer when it comes to determining the state of your business.
13. How would you go about fixing an autosuggest problem in a developing nation?
The following actions would be taken to fix an autosuggest problem for searches in a developing nation:
- Select the most popular keywords in your nation, and then use live autosuggest results to see if those terms could work as suggested search terms. You can also try different abbreviations and other strategies.
- Before rolling it out on a larger scale, look for comparable nations or areas where you may test it first.
14. Create a Java program to reverse a string using recursion.
public class Main
{
//Driver Code
public static void main(String[] args)
{
//Initialize the String
String str = “Reverse String”;
System.out.println(“The entered string is: ” + str);
String rev = reverseString(str);
System.out.println(“The reversed string is: ” + rev);
}
//Recursive Function to Reverse the String
public static String reverseString(String str)
{
//If entered string is empty
//Return the empty string
if (str.isEmpty())
return str;
//If string consists of multiple character
//Call the Function Recursively
return reverseString(str.substring(1)) + str.charAt(0);
}
}
Output
The entered string is: Reverse String
The reversed string is: gnirtS esreveR
15. Write a Python program that uses sets in a given string to count the number of vowels.
def vowel_count(str):
# Initializing count variable to 0
count = 0
# Creating a set of vowels
vowel = set(“aeiouAEIOU”)
# Loop to traverse the alphabet
# in the given string
for alphabet in str:
# If alphabet is present
# in set vowel
if alphabet in vowel:
count = count + 1
print(“No. of vowels :”, count)
str = “WelcometoSLA”
# Function Call
vowel_count(str)
Output
No. of vowels : 5
16. Write a C# program to remove whitespaces in a string.
using System;
using System.Text;
class Demo {
static void Main() {
// Initial String
StringBuilder str = new StringBuilder(“Patience is key!”);
Console.WriteLine(str.ToString());
// Replace
str.Replace(” “, “”);
// New String
Console.WriteLine(str.ToString());
Console.ReadLine();
}
}
Output
Patience is key!
Patienceiskey!
17. Write an algorithm to print the X star pattern.
The X star pattern:
* *
* *
* *
* *
* *
* *
*
* *
* *
* *
* *
* *
* *
Algorithm:
- Start
- Construct a Scanner class instance.
- To keep track of the number of rows, declare variables.
- Request that the user set the initial row count.
- The design can be printed using a for loop.
- When j=i or j=k-i+1 displays “*,” the inner for loop iterates from j=1 to k and prints the charter; otherwise, it displays space.
- This code will run until the condition of the inner for loop is false. Afterwards, it will go to the outer for loop, where it will continue to run until the condition of i<=k is false.
- Present the outcome.
- Stop.
