Interview Preparation Tips
Experience: First round was a written test which had 20 MCQ's in the field of Databases, Theory of computation, Operating systems, Data Structures and Algorithms and one programming question. 7 students (4 B.Tech, 3 M.Tech) got through to the interviews. Most of the interviews were held in the Google Bangalore campus. There were a total of 5 rounds of interviews. All based on Data Structures and Algorithms. Each round had 2 questions for which we were usually supposed to explain the algorithm first and then write the code on a Google doc. It was a really great experience. I got a chance to visit both Google Bangalore and Hyderabad campuses and taste their awesome food.
Total Questions: 20
General Tips: Practice your coding skills. Writing a neat code is very important. Interviewers not just look for a good algorithm but also your coding style (indentation, variable names, simplicity etc.)
