Google HC, On-Site

Hi guys, I recently went through the interview process at Google and currently waiting for results. I know Google is slow in hiring and I am trying to take my mind off it, but few things are bugging me from quite a while and I would really appreciate if some of you who know in's and out's of the process can help me with my doubts. I received a call from recruiter in late Nov 2020 for a Web Solutions Engineer role. Although this wasn't the position I targeted for but I went ahead with it (as currently I am at a very low compensation) and cleared the phone screen by second week of Dec. After that my onsite interviews were scheduled in early Jan 2021. I had 3 virtual onsite interviews, 2 of which went well and by well I mean I came up with optimal solutions explained my approach and thought process really well and made no mistakes in my code as well as answered all the follow-ups. The 3rd interview didn't went well, here I struggled in the warm up question itself and could only code the brute-force for some reason, however the weird thing is I came up with optimal solution to the main question with just 1 hint in no time but didn't had time to code. I was expecting a rejection mainly because of this last round but after 3 days recruiter called me and said the overall feedback is solid however before she could send the packet to HC I need to give one more interview. I felt a bit relieved that I still have some chance and the last interview was scheduled after 1 week. Coming to the final interview, I would say I knocked this one out of the park, I mean I too was impressed by my performance. The interview started with introductions from both sides and took roughly 10 mins, in the next 25 mins I solved and coded 2 medium problems with optimal solutions although the interviewer intended to ask just one. He said that he is not allowed to ask more than 2 problems in an interview and so for the last 10 mins we just chatted about his team and role at Google. It's more than 1 week now and I haven't heard back from my recruiter. What are my chances of getting an offer at this point. Will that one bad interview ruin my chances? I would like to add that all my interviewers were senior people with around 7-10 years of experience. Also, when I am likely to hear back? Thanks #google #tech
