Pros
Still trying to figure it out.
Cons
Ever walk into a Mom and Pop shop they expect you to know everything. This is exactly that. No training curriculum, HR benefits is spacy, and to learn business operations is a joke. They tell you to ask questions and then critize you later for "reiterating" and pulling you in 50 different directions on top of you under salaried job with many hats. I'm going to be nice and stop now and just advise. There are better opportunities, with more pay and less responsibility. Also be careful of a vindictive business owner/shark. You will only prosper if you are working 80+ hours a week. Even thought you agree to 40.
Need not apply if you are Indian.
