The best way to prepare for a job interview in Spain is to research the company's website or reference books. Job requirements should be carefully reviewed to ensure that all the important issues can be addressed in the interview. The language for business in nearly the entire country of Spain is Castilian Spanish, except in the south. Interpreters are available, but it is preferable to have a basic knowledge of Spanish to do business in Spain because the second most common language is French, not English.

Spaniards tend to be very conversational and there is always casual discussion before entering into business. Personal relationships are very important, both socially and in business, as this helps to establish trust. Initial interviews in Spain are very short and intended to establish initial impressions for both parties. This is where it is most important to make a good impression to ensure a return interview.
