After I sent my CV, a recruiter contacted me. She was walking me through the whole hiring process. She helped me to solve problems: I got ill and asked to reschedule an interview. Also, I had a group call with other job applicants and Google employee, who gave me detailed information about an interview. Eventually, I had two interviews with two engineers, each of them took about 45 minutes with 15 minutes break. I had to solve a few algorithms tasks by writing code in shared Google document and I optimized one of them. In the end of each interview, I asked a few questions. A week and a half later or so I`ve got a refusal.
