Pros
A great feeling that you are working for some great cause(which will last only for a few days). You might get good work but chances are very low that you will be able to finish it properly.
Cons
The worst workplace you can ever find, no Future plan, no goals, no revenue, no business plan, no funding. Top management is good at only one thing, Micromanagement. They Don't trust any employee and treat them as slaves who will just follow orders from some self-claimed AI Experts. very toxic culture, no one looks serious in the company including co-founders who will come to the office just to micromanage and demotivate people that's it, their only job is to give false promises, and spread negativity in the office. All the great people have already left the company and whoever is stuck will leave very soon, it is a sinking boat don't even think to join this. No WFH(Reason for this- what if someone will steal your laptop, A 3rd class laptop, wow), different policies for a different set of people, office environment looks like a circus. My prediction - This company will shut down within a year.
