Google Quantitative Analyst interview questions

Was contacted by linkedin recruiter. Did initial questionnaire about programming and big data experience. They set up a google hangout interview - did preparation with recruiter to have computer set up and studied suggestion material (by recruiter). Interview happened via phone-call (not video). Was contacted shortly after saying they did not want to move forward.

An employee send them my CV and a recruiter contacted me the next day with a questionnaire of 13 questions asking to describe a project, what language I use etc. Questions that are typical in an HR interview. Then they moved me to a phone screen. The interviewer was very friendly asked me in the beginning about the research in my PhD and the 3 questions, one probability question, one coding questions and then described a scenario and we brainstormed on this; ended up a two-sample proportion hypothesis test. After a few days they moved me to an on-site interview that it took a while to schedule though. The on-site included 4 interviews, some of them heavily on the probability and statistics side (you must be well prepared!), on practical problems and some coding questions as well. All interviewers were very friendly and down to earth!
