Pros
They are making money, sort of.
Cons
The company says it's hiring a full-time senior software engineer, but really is just hiring people for a 1 month trial period. It's really a dishonest practice. If you are assigned a task, there will be no story with acceptance criteria and background info. If one asks for it, he will be told this is a startup, you are on your own. Also developers have no access to the repo, and only some of the code were shared. Code reviews will be done by emailing code to the CTO. So no access to all the code, and no formal checkin/code review process. Also training is non-existent. Newly hires will be given a lecture by the CTO on this is a startup, and if you are blocked, just deal with it because life is tough. Multiple times, something will be told to the developer at the last minute (like using a hitherto unknown function unavailable to the developer) and frantic changes would have to be made to make the deadline. In their 7 years in business, they only managed to retain 1 developer. Any suggestions made will be ignore, on the ground that this is a startup and no one has time to make changes.
