I live in a country where working part-time, you will not earn a living, only for food and paying for house/apartment expenses.
When applying for a decent job (not as a laborer) for a full-time job, it is taken into account first of all (relevant for the country in which I live, in other, more civilized countries, the requirements may be more humane):
I.
1. Work experience;
2. Education (if you are not a programmer in the USA);
3. Actual knowledge and skills, the ability to apply them;
4. Sociability;
5. Appearance (physical and mental health);
6. Willingness to work in the company for at least 3-5 years.
II. Attention! Perhaps this is relevant only for my country!:
If you want to get a job in a large business company, you should be prepared for the fact that you will be checked by the Security Service on a lie detector (for example, as it was with me), you may be asked the following questions:
1. about sexual orientation (in my country it's possible! I have not been asked such a question, but some of my friends - yes);
2. Do you use alcohol or drugs?
3. are you ready to build a career in the company?
4. Are you ready to really work, as required by the employer?
5. do you drink alcohol only on holidays? How often do you drink alcohol?
6. Do you have chronic diseases? If so, which ones?
After you pass the lie detector, the experts (professional psychologists and former law enforcement officers/intelligence officers) will send their conclusion to your employer (they work for the employer!), and the employer will independently decide on the basis of this conclusion whether to hire you or not.
If you refuse to sign all legal papers for the consent of passing a lie detector - that you pass it voluntarily in accordance with the Law, then they will tell you - goodbye!
Perhaps in Western Europe and the USA there is a completely different, more humane system, but in my country everything is exactly like that!
There are practically no homeless people in my country, because in large cities they are beaten by the police and arrested (if they find drugs).
In my country, drug addicts are jailed for 10-15 years (if there are no connections in the police, or influential parents who will get rid of criminal prosecution for a bribe (as it was with a friend of my relatives, his dad saved him from criminal prosecution)).
In my country, prostitutes/girls of easy virtue can be raped by police officers right at the police station.
