Vantaggi
Upper management is not very smart so once you figure them out they're pretty easy to dance around. Outside of sales, every job in the building is basically a sandbox. If you're new to web design or front end dev or SEO/web marketing, it's a fairly consequence-free environment to learn while getting paid (significantly under market value). Yes, you might get yelled at by a mostly inchoate baboon or two, but the world inside of iNET is entirely separate from the real world. No one really knows it exists, and the people who do regard it as a joke, so just learn everything you can while you can tolerate it, then move up to something better as soon as you outgrow them.
Svantaggi
First things first, in the time I was there the turnover rate was above 100% per year. The cons are innumerable, but the one thing that arches above them all is that you will never, ever, ever make a market-rate salary. There are no shortage of terrible web and marketing firms out there, but at least some of them make up for it by throwing money at you to ignore the problems. Not here. Even when they agree to pay you more, it's usually attached to some kind of impossible condition. As I said above, it's an ok place to get your feet wet, especially if you're new to the field or lack experience, but don't believe them when they try to tell you you'll never succeed anywhere else. They have no pull with anyone of consequence and have no power over your career outside their walls. Oh, the CEO once wrote a 5,000 word article for a hobby magazine wherein he spent at least two-thirds of it deriding a pair of employees with unnecessary personal insults. He is a special kind of insecure snowflake.
