culture... in which ways have you found it to be a huge factor?
It's all about the stereo types
Would you outsource your book keeping to someone in Nigeria ?
Culture differences and stereo typing are a type of indicator good or bad on what could be expected from a freelancer. My opinion is this comes from strong family units / communities, regional politics and religious backgrounds.
For example Many of the Filipino freelancers I work with are religious, have strong family units and are their households primary source of income.This makes them put a lot of value on job stability giving the majority of Filipinos a hard working and Loyal mindsets.
This is where the culture makes a difference. You wouldn't want to hire a Filipino part time regardless of how much you pay. To them part time is temporary. It's viewed as if you don't have enough work for them and it could stop completely at any time. They will continue to look for other work.
Hire full time and keep a steady flow of projects going and you'll be amazed.
Compared to an India freelancer that has no preconceived ideas about part time work. In my experience they've been satisfied with a well paying part time gig.
India is made up of many different cultures much like the USA has west coasters, mid west and east Indians are more entrepreneurial than Filipinos. They are more willing to take risks.
Ive had good experiences with outsourcing to India but more bad than good.
How you handle the cultural differences can effect the quality of your freelancers output more than you would expect.
