Experience:

Vaibhav Pandey shared his Google Software Engineer interview experience on GeeksforGeeks. The process was described as exciting and challenging.

Round 1 (Technical Screening): This video call was conducted by a senior engineer and covered data structures, algorithms, and problem-solving. Questions included: "Implement a function to find the intersection of two arrays" and "Given a binary tree, find the maximum depth of the tree." The interviewer was patient and provided hints.

Round 2 (Coding and Problem-Solving): An in-person session where the candidate was given challenging coding problems and asked to write efficient code on a whiteboard. Topics covered included strings, linked lists, and dynamic programming. An example question was: "Given a string, find the longest palindromic substring." The interviewer encouraged the candidate to verbalize their thought process.

Round 3 (System Design): This round involved a real-world scenario requiring the design of a scalable and efficient system. The discussion encompassed various components such as databases, microservices, load balancing, and caching. The interviewer critically reviewed the design choices and offered constructive feedback.

Round 4 (Behavioral and HR Interview): The final round focused on behavioral questions, inquiring about past experiences, approaches to problem-solving, and how challenges were handled.

Overall Experience: The experience was intense yet fulfilling, with knowledgeable and supportive interviewers. The candidate received positive feedback and ultimately an offer from Google.
