Google Quantitative Analyst interview questions

On-site interview at their London office. Had 3 interviews in total, 2 of them were video conferences. Each was 45 minutes. Everyone was very nice. They tried to gauge how much you know and if you don't know a particular area, they'll ask something easier. So it's hard to say how much I could have done more to land the job.

Internal referred followed by two round of phone interviews. Both interviews focuses on technical questions. The first interview has lots of questions on the fundamental statistics models, such as regression models, experimental design. The questions are like typical exam problems, but requires quick instant responses. The second interview also fucused on statistical questions, but were asked in a practical context. The interviewer described several projects with me, and for each project he asked questions about how you would like to plan the project, what models would you use, what were the alternative choice you have, reasons you picked that model, etc.
