Hi im a high school drop out and currently having a business idea,can anyone tell me how can i start something without having much knowledge about it?

What are the requirements to hit and internship with a Private Equity Firm in Malaysia? Being very interested and excited to get to know more about Private Equity, and knowing that the barrier of entry is high, how could I get in as a fresh graduate next year? And what Private Equity firms out there are hiring interns?

I have got a job offer from a international well-known mobile phone manufacturer company. The work location is at Dubai. It sound attractive with their well-known brand and remuneration. But during the stages of documentation compilation and related pre-employment arrangement, they shown me very unprofessional working attitude and it has affected me so much until I have feeling reluctant to join. Of course, I will need to invest at least RM 10K on the initial to join the company make me feel the pain as well. But I am still admire with their brand name and the overseas job opportunity. I am do not know what should I do. Hope someone can guide me here. Appreciate it.
