Looking for a work placement is a task that can be more or less complex, depending on the circumstances. It requires advance preparation and a selection of the right sources of information.
The most common and most fruitful method is based on a network of acquaintances. You should explore your options by talking to your family, friends and acquaintances as much as possible.
A number of establishments also have structures that are designed to provide help in the placement search process. They are often little-known, so check with administrations about the existence of this type of structure. Professors can also be a very useful source of information. They may have helpful contacts through partnerships with industry on research projects that could simplify your search. Another source within your school is its alumni association, which may have contact information for graduates who tend to be very interested in taking on trainees from their alma mater.
In terms of outside sources, social websites and networks like LinkedIn can be of tremendous assistance. It is often necessary to have a direct link to the recruiter in order to be selected for a placement; sending email has a very low success rate. Using a social network or having a direct telephone number can significantly increase your chances of getting an interview. There are also recruitment agencies and CCIs that post work placement openings. These are worth looking at, but make sure you are not being assigned the work of a full employee.
Lastly, if you are interested in a placement abroad, companies are often discouraged by the cumbersome bureaucracy associated with issuing a visa. To target your search, contact cultural centres and embassies who may be able to simplify the process substantially.
