Elaborate how you can crack a technical interview at Google. Share how the interviewing process works at Google. The qualities Google looks for in candidates. Topics covered in a Google interview, Google Interview Process Every candidate’s evaluation process differs given that interviews are conducted by different recruiters and interviewers and questions asked differ based on the role applied for.
Based on our research, we have outlined below, the interview process as followed by most candidates at Google.
1. Initial phone screen with a recruiter
a. Phone Screen by recruiter
This is the first part of the phone screening process. You will be contacted by a recruiter who will go over your work history. Many candidates get eliminated at this stage so you shouldn’t take this round lightly. Technical questions may be asked, on topics such as Quicksort and Bubblesort. Answering these efficiently will get you to the next round.
b. 45-minute technical phone screen by an engineer
Only 1 in 10 candidates succeed in this part of the phone screening process. You will be asked basic coding questions about projects you’ve worked on. You might also be asked to solve a problem using Google docs.
c. 45-minute interview with an engineer
In the final part of the phone screening process, you will have an interview with another engineer in which you will be asked another set of technical questions.
2. Onsite interview
The onsite interview process comprises 5 rounds, each 45-minutes long. Additionally, you will also have an informal lunch interview. During these rounds you will be asked to solve a variety of technical problems on the white board, laptop, or both

Qualities Google Looks For In Candidates Google expects their job applicants to be proficient in at least one programming language; preferably C++, Python, Java, Go, or C. You will be asked interview questions from a wide range of topics, such as APIs, Objective Oriented Design and Programming. Be sure you have a conceptual understanding of these topics.
Problem-solving is a key skill Google interviewers look for in its candidates.
Effective communication skills Besides being well-versed in programming skills, you also need to be a good communicator. Google values individuals who can communicate ideas in a clear and concise manner. You will also need to be a good listener as well given most roles involve working with or in a team.
Know how to write code and solve algorithmic problems on a whiteboard During the Google onsite interviews, you will be asked to design algorithms on a whiteboard. As compared to writing code on a computer, it is a completely different experience. Train yourself with either paper or an actual whiteboard if you want to increase your chances of success at the interview.
Google looks for candidates who can take on challenges. Excelling in this facilitates strong teams.
Google calls this “Googleyness.” Google’s hiring managers will observe how comfortable you are with ambiguity. They will also keep an eye on how you work individually and on a team.
Qualifications for Roles at Google We looked at Google’s career website for job descriptions of roles we see our students aspiring for.

Experience designing and implementing distributed systems. Preferred qualifications:
12 years of relevant hands-on technical management experience of software developers and systems administrators/architects. 5 years of experience in leading highly-complex, technically-challenging, cross-functional software oriented projects from inception to delivery. Track record of individual technical achievement. Excellent C++, Java and/or Python skills Google Interview Questions It is important to note that Google, like all other top tech companies, have a number of interview questions that they rotate between. Questions are also frequently removed from the rotation, and replaced with new ones on a regular basis.
The most effective and efficient way to prepare for technical and behavioral interviews at Google is to look for conceptual themes and patterns, rather than trying to identify commonly asked questions.
If you want to ace interviews at the most competitive companies, place emphasis on pattern recognition and building your problem-solving skills. This is the only way to solve problems that you have never seen before and the only way to fully explain your solutions during interviews
To understand interview question patterns, here are some of the most common questions asked at technical interviews
Technical Questions
Demonstrate how to reverse a linked list. Find the formula to solve an nXn Magic Square problem. Search a max value in an unsorted array in better than O(n). Find out the fastest way to locate the largest element in a circular sorted array. How do you convert a max heap to min heap? How will you implement three stacks with one array? Can you design a data package transfer from London to Tokyo? Can you write code to implement your own hashtable in C++ or Java? Do you like coding or designing applications? Given an array of size n, find the majority element. The majority element is the element that appears more than floor(n/2) times. You may assume that the array is non-empty and the majority element always exists in the array. Given a 2D binary filled with 0’s and 1’s, find the largest rectangle containing all ones and return its area. Bonus if you can solve it in O)n^2) or less. Given a string A, partition A such that every substring of the partition is a palindrome. Return the minimum cuts needed for a palindrome partitioning of A. Given a string A and a dictionary of words B, determine if A can be segmented into a space-separated sequence of one or more dictionary words. Design a messaging service, like Facebook Messenger. Given two numbers represented as strings, return multiplication of the numbers as a string. Design a search typeahead (Search autocomplete) system at Google’s scale. Given numRows, generate the first numRows of Pascal’s triangle. Pascal’s triangle: Generate A[C] in row R, sum up A’[C] and A’[C-1] from previous row R - 1. Given an array of integers, sort the array into a wave like array and return it. In other words, arrange the elements in a sequence such that a1 >= a2 <= a3="">= a4 </=> Given 2 non-negative integers m and n, find gcd(m, n). GCD of 2 integers m and n is defined as the greatest integer g such that g is a divisor of both m and n. Both m and n fit in a 32 bit signed integer. Behavioral Questions
How do you execute a project? Explain a technical challenge which you overcame. What is your favorite Google product? How would you improve it? How would you deal with group conflict? Explain a situation in which you had to learn something you didn’t know while working on a project. How do you sort priorities when engaged in multitasking? Do you prefer earning or learning? Tell me about a time when you effectively managed your team to achieve a goal. Explain your approach. Tell me about a time you failed. How did you deal with this situation? Tell me about a time when you faced a problem that had multiple possible solutions. How would you deal with a non-cooperative coworker? Sources:
Google Interview Tips Here are some handy tips to help you get through interviews at Google.
During the phone screen and onsite interviews, think out loud and speak as clearly as possible while solving a problem. Explain your thought process to the interviewer. It is important to consider edge cases and test your code, even if it is a simple problem. Not doing so will have a negative impact on your assessment. If you’re unable to solve a problem right away, slow down, simplify the problem, challenge your assumptions, and keep attempting to solve the problem from many different angles. The interviewer might even give you hints along the way Don’t be afraid to ask your interviewer clarifying questions about the problem. Be prepared to share specific examples and stories of what you’ve done or accomplished in your professional career. Always repeat the question in your own words and clarify the problem requirements. Doing so helps demonstrate your comprehension of the problem. If time permits, improve your solution to the problem. Use a whiteboard to draw examples like an example array or binary tree. Prepare two or three questions to ask the recruiter and each of the interviewers (including technical interviewers) at the end of each round. You can ask multiple interviewers the same question. For the phone screen round by the recruiter, read up on the role and company ahead of time. Google Interview Experiences To understand how it is to interview at Google, we studied first-hand experiences of candidates who received job offers from Google.
From an ex-Google software engineer
“I was given the option to use a laptop if I wanted to, which I did. As a side note, I would highly recommend that if you are given that choice or option, take it. Personally, I think that it’s just far easier to actually write out code on a laptop than it is to do so on a whiteboard and the beauty is that you can actually use both.
That first interview was very interesting...two things stuck out to me that was interesting. The first is that during the sort of introduction of the interview, we chatted about my projects on my resume...Put at the top of your resume the things you are most proud of that you think are going to be the most impressive...the second thing is at the very end, the last lets just say 10 minutes, we had this sort of discussion about parts of the interview.
The second interview went very, very well. I remember that interview was sort of like the interview where it just went well. I knew I was able to come up with a solution immediately able to come up with a pretty optimal solution to optimize on that of that and then optimize it even again on top of that.
The third interview was very similar to the previous one. Maybe a notch lower. I came out thinking I did well.
Just a normal lunch interview. It will have no bearing on your application. The person I had lunch with ended up being on one of my sibling teams at Google once I worked there. Apart from that, nothing special.
Then the fourth interview came along and I vividly remember finding that particular interview very difficult. I remember thinking, “wow, these engineers don’t kid around.” But I also remember coming out of that interview very good and feeling like I had done very well.
What I did in that interview, which I always recommend that other people do is I really treated it as I am with a coworker, we have been given a problem we have to solve together, but I am the one leading. I am the one doing 80-90 percent of the work but I’m sort of trying to have a conversation with this coworker of mine. Here, I am speaking about the interviewer and I’m just going to try to solve this with him...Two people [just] working on a problem together.
Finally, the fifth interview, nothing too special there. It sort of felt similar to the first interview. I came out of it feeling neutral.
Finally, I got the phone call...it was very positive and I’d gotten a hiring decision from the hiring committee.
The final hoop after matching with a team and manager is called the ‘Vp and SVP sign off.’ They have to review your individual packet and sign it off.”
Interview with Divanshu who got into Google, Mountain View
“According to me, all the four interviews had a similar difficulty level. During all the interviews, the difficulty bar was raised slowly as we approached the end of the interview.”
I was required to send all my grade cards after one week of the interview process. Then they reviewed everything and the offer was given. So, I believe that grades were also a factor involved in the selection process.”
