Google

I got this selected for the interview rounds for the position of Google SDE Summer Intern 2027 after finishing in the top 1500 of Google Big Code test. I gave the test in March and the recruiter emailed me in june if I was interested for applying for working with Google as a summer intern. I applied and got selected for the interview rounds. The first round is not a standard interview but just a 15 min session where the recruiter went through my resume and asked me about my projects and how much DSA I did. She also asked about how many questions I did on leetcode and looked at other platforms like Codeforces and Codechef. This session's main purpose was probably for the recruiters to check if you were legit or not. I got through this round. We then had a prep session for the next 2 main rounds of interview. Each interview round is of 45 minutes. It is broken down into: 5-10 min of introduction, basic questions and if the interviewer is interested he/she can ask about your projects. 30-35 min which consists of 2 DSA questions. The topics include arrays, math, sliding window, two pointers, prefixSum, hashing, binary search, stacks, queues, graphs and Trees. Dynamic programming was told as not important so those questions weren't asked for anyone in the interview probably. The questions have to be solved on a google sheet which will be shared in the google meet and the interviewer will be able to see the live changes u make to the code. You will have to explain the approach like how you do while coding. You can also ask questions to the interviewer and get doubts clarified if question is vague (google sometimes makes this intentional to test the candidate). This means that properly able to communicate your thoughts matters as much as solving the question. The last 5-10 min is about AI questions. This is not a technical AI round where the questions will be about AI technologies it is about how AI can be used in professional workspace, how do you optimize tokens and other general AI usage questions. At the end you can also ask interviewer questions. Who got selected in the first round gets selected to the 2nd round of interview (The same DSA round). My interview experience: In my first round of interview the interviewer didn't ask any intro or any other questions and went straight into the question. 1st q: Imagine there are n people waiting in a line, all facing the same direction. Each person has a different height. A person A can see another person B in front of them if there is no one taller than both A and B standing between them. How many people can the last one in line see? this I was able to solve using the most optimal approach using an O(n) scan. 2nd q: How many people can everyone see? This is the leetcode q 1944 no of visible people in a queue. I got the stack logic for this but i wasn't able to fully code the solution. I got rejected after this round.
