Brazilians are quite smart people. They quickly perceive who is there to teach and who wants to earn some money for pocket needs, for the next leg of an adventure abroad. The people got used to everyone having secret motives; Brazilians are not the people to be cheated by foreigners, they themselves can do it even better. But despite of that, such qualities as sympathy, honesty, and a mere modicum of interest in the people are in value. Using all these teaching will be very easy and good for you; the students will be loyal to you.
It is better to set all the job conditions even before arrival, but most make a mistake coming on a student’s visa and than only beginning to search for real employment. English schools exist even in the smallest towns of Brazil, so your choice depends on the kind of environment you prefer for your teaching experience. For once, the big city does not necessarily offer better job opportunities.
In fact the reverse may be true; in a small town where real live foreigners are rare, you will be regarded with respect and gratitude for choosing to forego life in the big city - still the dream of so many country Brazilians. Indeed, Rio and São Paulo are very cosmopolitan cities with many resident native English speakers as well as Brazilians who have lived abroad, putting you at a distinct disadvantage professionally. Also, distances in these cities are huge; I can’t tell you what a pleasure it was to walk to work in five minutes in my little gaúcho town of Sapiranga.
Like all the large countries, Brazil has regional differences that may influence your choice of location. For example, The Northeast is the most African part of Brazil, with a colorful history and a languid, happy attitude toward life—despite the hardships of poverty. "The South" refers to the three southernmost Brazilian states of Paraná, Santa Catarina, and Rio Grande do Sul, generally considered the most advanced region, with a cooler winter climate and stronger work ethic than the rest of the country, thanks to the masses of European immigrants who have come to Brazil since the 1800s, from such countries as Italy and Germany, plus some Eastern Europeans. It is not at all uncommon to see blond men and women with German or Italian last names who still speak Old German at home four generations after their ancestors arrived. It’s ordinary to see mixed-race people with chocolate skin and light-colored eyes.
In 1999 national currency, the real, broke up hence it became more difficult to earn good money according to the western standards of living. In the province villages the wages of the people are quite low, but in town they are higher—due to the higher rate of the expenses. You are able to get a spare time job as a tutor, increase your income substantially; sometimes even twice.
