Google is a wonderful place to work, I wish I never left! As a TVC though, your experience is greatly dependent on what agency you are with. If your agency is timid about asking for more money so that in turn, YOU can continue to climb then you're out of luck. Everyone is pretty collaborative, easy going but hard working. My experience as a TVC was that they didn't care how or when you did something, as long as it was done and on time. You do have to get used to requests from FTE's that can seem frantic, I.E. "I need this YESTERDAY HELP ME PLEASE!" but if you can communicate and ease fears of trusting a TVC to complete a task, then you'll do well. Engineers there, both software and hardware, tend to lack communication skills or emotional intelligence so if you can bring that to the role then you'll be greatly appreciated. You get almost all of the same perks like free gym access and food however you do have to pay $1.50 each way on the G Bus shuttles whereas this is free to FTEs. All FTE shopping perks, concerts and happy hours are not extended to TVCs but its not that big of a deal. Overall, great place to be with the RIGHT agency.
Free meals, free gym access, great work/life balance and culture.
As a TVC, your experience and ability to thrive is dependent on who your agency is.
