Working for a company that offers business development services

Q: I work in an organisation named JKEDI which is an entrepreneurship development institute and its mission is to make youth self employed so that they attain financial independence as its very difficult to get a government job here and the unemployment rate is alarming. JKEDI trains entrepreneurs, offers business development services and provides them finance for starting their business by linking them to banks where they are charged interest and give loans directly also. I am working there as a trainer. I want to know whether my job is halaal or haraam. And in  case its haram, can I continue working here till I get another job or I should quit?

Doing an accounting job

Q: Is it permissible in Islam to have an accounting job? Or a financial analyst? Every company nowadays deals with interest. So avoiding it

Working for a company that is involved in making arms

Q: I am trying to find out for a friend the permissibility of working for a company that is mainly involved with making/creating arms and selling them to companies globally including countries that use them to kill Muslims. The companies main areas of business are Defence (80%) and remainder Space/Travel. He would be working in the IT division and would have no direct involvement with the defence areas of business. He has asked a few well known scholars who said it would be deemed permissible but wasn't able to get any elaboration/clarification as to how it was exactly permissible. The company is also involved in talks with creating an office in Tel Aviv.

Cooking at functions

Q: My wife and I assist with the cooking at functions for which we receive remuneration. At times, the functions are un-Islamic (engagements) and there is open violation of Shari’ah laws (e.g. intermingling of sexes). We are in no way involved with the function. We only assist with the cooking and kitchen. Is it permissible for us to assist with the cooking and is the money earned halaal?

Studying electrical engineering

Q: I would like to study and become and electrical engineer. I live in the UK and working in this field means doing the job in domestic homes, factories, outside work, in offices and business, construction sites etc. Also men and women mixing is unavoidable. There may be a time (whether it's continuous or not) when I have a female client for a home domestic job, or an office company where men and women mix and whose company is something haram or a mix of haram and halal, like insurance or entertainment, restaurant that may sell alcohol. 

My question is: Can I still do this work for clients or provide them my services who may sometimes be women or a business which is haram, as the work may be varied; so one day at someone's home who is a woman or a business whose dealings are either haram or mixed, and another day with men and with a business that is halal for example?  Do I need to be picky? My job would be to just provide them with a service and my intention would be to earn a living. Would my earning be haram in any way?
