What is the job market for international students in Czech republic?

Honestly, the job market is not good. The economy went from near full employment in 2007 to deep recession in late 2008/2009 and recovering slowly. While economy is growing again since 2010, the unemployment is going down not very quickly and it is still hovering around 9%. While in Prague you have the best chance to find job, in rest of the country you will not be very lucky, or you will be working for depressed wages. In summer times, the unemployment goes down, so if you were considering work in CZ, you should had come here in spring. However, by fall the job markets go down, as the tourism shuts down, and many segments of economy works only in warmer seasons (forest, mountains services, tourism) and shuts with arrival of first snow (usually in October).
