Google Software Developer interview questions

Very difficult, interviewer didn't come on time. They had rescheduled the interview again. Was asked only binary trees and linked list. Felt like he was least interested in the whole interview.

First a recruiter reached out to me via email and then we had a telehonic round about my hobbies and about my problem solving abilities then phone screen round initial technical round for eligibility to higher roles and next rounds in which dsa question was asked based on sliding window algorithm which i couldnt solve within the time constraint I had problem with communication and understanding the problem statement which led me for rejection
