There were 5 interviews 4 dsa rounds and 1 culture fitment round. In each dsa round you can be asked any number of questions depending on your speed to solve the problems. In one of the rounds I was asked 3 questions. Some rounds were very easy and others were rather difficult. In easy rounds I was asked to solve one easy to medium level question based on array manipulation. In other rounds I was asked to solve questions related to graph. One of the DSA round was rather difficult in which I was asked to solve a hard problem which was a modified version of one of the hard problems from leetcode. Culture fitment round was also different. I didn't get the offer as I wasn't able to solve that hard problem and also didn't performed well in culture fitment round. My advice for those preparing for Google is to focus on medium and hard level problems on leetcode and not to take culture fitment round lightly (the mistake that I did 🥲). Culture fitment round is most important of all and even if you perform Excellent in all dsa rounds and failed in culture fitment, you will not get the offer. All the interviewers were really kind and my advice is to not to stick to one problem if you're not able to solve it. Ask interviewer for hints. Also don't sit silent. First explain your approach and then implement the solution and keep telling what you're doing step by step.
