Google Site Reliability Engineer interview questions

This is for the Software Engineer and not the System Engineer SRE position. 1 HR screen, 2 technical coding phone screens and finally an Onsite interview. Onsite interview consisted of 6 rounds. 5 coding rounds and a 45 minute lunch interview. The SRE folks at Google seriously lack basic communication skills. The only thing they look for in a candidate, is if the the candidate can code like a trained monkey. Not one of the interviewers asked me about my background or even attempted to understand why I was genuinely interested in the role. Each interview will begin like "Interviewer walks into the room and the first thing he says is lets start coding". If you finish the coding in time they will entertain a few questions. But then again, it is completely a 1 sided interview. You are never given a chance to speak of how you would make a good fit for the role, or even what value you bring to the table. You're only job is to get the output. I solved all the questions I was asked and solved them in an optimal way, but i did not get an offer. For reasons which baffle me till today. I did have to think through some of my answers and double check my logic. But apparently this is not acceptable. I dont think the interviewers understand the pressure a candidate is under when there is so much scrutiny. You have to write the code and logic flawlessly the first time around with no room for error or correction. They dont care about the though process either. If you cant manage that, dont get deceived by their smiles you are going home to read a reject email from the recruiter. The SRE's really need to be schooled with the art of basic communication and manners. I really ponder how they would perform if the roles were reversed and they were under the gun doing the coding. The questions asked were of good quality no doubt. But the interviewers are just trained robots.
