Google Senior Software Developer interview questions

I applied online and a recruiter reached out the very next day to set up the initial call. I chatted with a couple of recruiters and they set up the virtual onsite interview based on my availability. They did share a lot of information about what to expect and it was perfectly accurate. The onsite consisted of 5 back-back interviews, 3 coding + 1 system design + Googleyness. I managed to solve all the questions in the coding rounds, but came up with an optimal answer at the very end for one of the interviews and didn't have time to code it. The system design was the most fun and it was more of two engineers discussing a design much like day to day work. Googleyness was the regular behavioral questions. All the interviewers were extremely nice and every one of them asked me if I needed a break before we began the interview. Recruiter contacted me within a week to tell me that my packet was going to the Hiring Committee. However got rejected at the HC stage, very likely to the one coding question I did not nail. Despite an unfavorable outcome, I still loved the experience and will definitely apply again in the future. As far as preparation goes, I'd recommend focusing on the basics and really understanding the standard data structures and algorithms. The questions asked were not difficult as such and it was more of a twist on the leetcode style questions presented as a real scenario rather than the vanilla coding questions. It was pretty collaborative and they do give you hints if you start straying in the wrong direction.
