Work / Travel costs to Warszawa (Warsaw) for interview for foreigners [6]

hello everybody!

I applied for a job in Warsaw and I've been asked for an interview. The job is advertised by a recruitment agency, told to be in a big international company and requires also the knowledge of two foreign languages other than Polish(not impossible maybe but not very easy to find) + English.

as I don't live in PL I would have to travel more than 1600 km one way and spend a lot to sit interview in Warsaw I asked if they cover transport cost, the answer was negative.

I know in similar situations travel costs are covered. Would not covering such expense be a common practice in Poland? Was somebody in similar situation?

thanks!
