Google Summer Intern interview questions

Applied with no referral. Passed the OA, then had to fill in a lengthy questionnaire, take two different technicals, passed both and was put on team matching stage, Did not match with a team. entire process from application to final rejection was about 6+ months.

One OA round and 2 Technical rounds. The OA had 2 DSA questions in 90 minutes and the 2 Technical Rounds also had 2 questions based on Arrays, Binary Search, Trees and Graph. I had to improve the time complexity of each solution I coded.
