Pros
Great pay and benefits. Office full to the brim with amenities. Despite tracking badge swipes to enforce hybrid work policies, my manager and team was very flexible. Work/life balance was some of the best I've experienced in ad tech. If you get your work done, no one cares very much where you are.
Cons
I can only speak to the Google Ads/DV360 side, but I felt extremely isolated. Virtually everyone that I worked directly with was distributed across the country, which felt at odds with the hybrid, 3 days a week in-office schedule. The people I sat alongside who were in my same role (or adjacent roles) were nice, but it didn't outweigh the fact that I was commuting just to send emails to colleagues and clients in other time zones. If I'm going to be in an office, I value community, and instead I felt totally anonymous. Nobody cared when I came and left which, while beneficial for doctor's appointments and the like, got old really quickly. I might as well have not been there. Additionally, I felt the culture prioritized and rewarded tenure above all. Granted, I recognize I was in a difficult position as the first new hire for my team in a few years. They had gone through rounds of layoffs in years prior. The next newest person on my team after me had at least 3-4 years of Google experience, and most on my team were nearing 7-10+ years. In my experience, the greater the tenure, the more people felt like they could talk down to you--never explicitly, but implicitly. I regularly had Account Executives on my team dictating emails for me to send to clients, completely overhauling decks I spend multiple days on, not looping me into important conversations, etc. It was as though I had no work experience prior to Google, like I just walked through those doors having never done any client-facing work. As if Google is some particularly special place--it didn't feel that special to me. I'm sure many people would enjoy this type of environment, but I did not.
