Avantages
I have to echo many of the others who have mentioned that a lot of people who work here are smart, interesting and creative.

Inconvénients
Anyone with a broad spectrum of experience other agencies or walks of life prior to joining the company was incredibly undervalued.
Despite seeming organized and on the cutting-edge, the foundational business practices were not just confusing but couldn't possibly be successful - for instance, there was no actual time tracking so everyone was wildly over or under-allocated and accounts were either wildly over or under-servicing. It was very clear that the executive team didn't have much experience themselves.
When I started, vacation days were "unlimited" and employee's were reimbursed up to $2k for insurance OOPs. Those unlimited vacation days was blatantly only a perk for the most tenured employees and no one else. When the health insurance requirements changed, we all took a $2k hit to our compensation packages and despite multiple questions on the matter, the issue was ignored by management.
A lot of decisions that impacted the company (like health insurance) were done through Slack voting, which seemed insane.
The sale to a holding company was quite disappointing.
All of the work is content work. Period. And most big efforts are just opportunities to increase the Creative Director's portfolio, regardless of sound strategy for clients.
If you want your entire life (including your social life) to revolve around ISL, you're golden.
