Pros
Invisible provides a well structured onboarding for partners, a fast company computer, and Slack. You'll interact with a lot of very interesting people coming to this new industry from diverse backgrounds, but you'll never really get to know most of them because they're putting out fires or they leave at at a year of tenure after their equity vests.
Cons
Although the company just disclosed its fundraise, they've had continuous layoffs in the background for the past year, leaving delivery ops shortstaffed and miserable. Heads have rolled in ops over morale and employee engagement, but nothing has really changed. The company culture is pretty abysmal: there's a universal allergy to accountability, a sweatshop-like environment for the agency and lower level partners, and bigheaded/overfunded clients who don't communicate well and build AI slop machines that you'll feel pretty icky about while you're interviewing elsewhere and answering questions about this position. You'll learn not to refer your friends here because after a 5-interview cycle, at the offer stage, recruiting will insult them by claiming that the position isn't available anymore, offering another position 1 or 2 tiers lower, and falsely insinuating that company growth will take care of their promotion to the original title in time (this is a common tactic). Career pathing is nonexistent; management will essentially tell you you're on your own to figure it out.
