Google Software Engineer - Internship interview questions

Firstly, an online assessment is needed. Then, I go through 2 phone interviews, asking about algorithms and data structures. The timeline was a bit longer compared to the other companies. HRs are responsible and interviewers are nice.

One coding challenge, three phone interviews. The average difficulty for the phone interviews was medium but one of the questions I received was very hard. Got into host matching but was swept by another company before I was matched. The HR was very fast and responsive!
