Google Operation Analyst interview questions

I was interviewed by 5 interviewers one by one. I went one time on-site interview while other interviews were done by video conference in the Google office in my home city. They scheduled the interviews efficiently. They asked me to listed out 5 problems of one Google product now facing. Then, they asked me the solutions to these problems. They asked me to tell a creative approach I used in my previous experience. Their feedback was good and we were about to start the hiring procedure but I guessed they chose another candidate in the end.

Interesting but the position did not fit my background
