Google Software Engineer, University Graduate interview questions

I applied online. Got a mail from google with coding test. The test was based on String Manipulation and Dyanamic Programming. The test was pretty much solvable and later after a week, I got a mail from the recruiter for a phone interview. Till now I have cleared the first round. I have 2 weeks to prepare for it.

Referred by a G employee. Got a snapshot coding challenge and survey within a week, completed it and moved on to the phone screen. Phone screen was with an engineer, took 45 minutes. Passed phone screen, moved to onsite in Mountain View. Had 4 45 minutes interviews, with a lunch break. Questions were not difficult, leetcode medium style. Heard back a week and a half later from recruiter, didn't pass hiring committee.
