I have an onsite interview at google in comming weeks and the focus in test engineering at Google. Any one else has experience related to test and test automation questions in a Google Onsite interview?

Update:
I had the F2F (via hangouts) interview in middle of March and was rejeted a week after. The main reason was that I stumble in system design and coding interview. The recruiter told me to focus more on

• System design: I clarified the requirements quite well and they were quite happy but while talking about how the data will be stored distributed DB, I stumbled.
• Test Automation: It was also a system design interview and was asked to come-up with test strategy to test a distributed system (Component level and E2E + test environment)
• Practice more in coding: I asked the carifying questions but one main requirement I didn't clarify which I realized while writing the actual code.
