Pros
Uh... well, I worked there for a while and I did not die. I guess that's a pro, right? Am I at 20 words yet?
Cons
Wow, where to start?
The project is essentially a vanity play of the CEO who got very lucky in an exit during the height of the dotcom boom in the early 00s. He has literally no idea what he is doing, how a startup works, or what he wants the product to be.
Basically, the team is made up of people who can't find jobs in other places, so management (that is, the CEO) thinks that they can pay very little (which they do). Zero benefits of any kind. Zero paid time off.
Will constantly dangle "equity" carrot in front of employees, but never actually execute. I've seen management set up impossible tasks for employees, simply as an excuse to fire them when they fail.
Management has no idea what it wants the product to be, so they never decide on anything. Meetings lead to meetings lea to meetings, and then the CEO gets this GREAT idea and scraps everything and suddenly two weeks' worth of work is down the drain. Then, you'll end up working a ton of hours with no light at the end of the tunnel, because the milestone gets thrown out.
Management consists of the CEO's friends from Israel who have no idea what they are doing.
Exploitative use of unpaid interns is rampant, as is misclassification of employees as contractors. Did I mention that management is extremely cheap?
Literally zero chance of career development or advancement.
