Google Sr. Software Engineer interview questions

Five interviews with two interviews on coding questions, two interviews on system design, one interview on behavioral questions. The interview process felt random with no relation to the interviewee's experience. One interviewer asked a coding question with mistake in the question formulation itself.

it's not easy nor hard, I already had a job so it was more of an internal promotion rather than a true interview. Very laid back overall. Would recommend interveiwning yourself at is it most rewarding
