TLDR: I've gone through Google's full interview process twice, and I had a poor experience both times.
TBH, Google is starting to feel like a bad ex-boyfriend. He is noncommittal, takes days to respond to my messages, and constantly ghosts and zombies me. He keeps promising that if I give it one more chance, we can make it work. Apparently, it takes him 2 to 3 tries to make it stick with past girlfriends. And that's a real Google stat! So, he'll convince me to go through the whole heartache again. I get my hopes up, do my best, and then it's the same old thing...he's borderline rude and stuck-up, and then he pulls the disappearing re-appearing act. In his latest late-night text, he was PLEADING to get back together (i.e.,: interview for a role), and when I responded...radio silence.
Recruitment: I tried to tap into my recruiters' expertise but had a really hard time getting prompt responses or feedback from them. In both interview cycles, I worked with my recruiter to select strong case studies for my portfolio interview, but when I showed up at the interview, they thought my case studies didn't showcase my expertise. If I'd just ignored my recruiters (they don't get UX research!) and gone with my gut, I would've selected another stronger case study.
Interview process: It was a mixed bag. I spoke with some people who were personable and thoughtful. I also spoke with some people who were downright hostile (read hostile, not awkward) from the moment they walked in the room to that unfortunate moment when I was trapped in the elevator with them. It didn't leave me with a good impression of what it'd be like to work there.
