How is life in IT support centres in Barcelona

Hey all,



I'm from France, working right now in ireland in an IT support position, single with no children. I have just been proposed an interview for IT job in barcelona. It is a network support role, english and french required, with day and night shifts, in an european service centre support Protected content . I don't know yet the company. It seems that the salary could be up to 35k euros. 
I also would like to settle for long time in my next life/job. Last point I don't speak castilian and catalan yet :) Id love to learn either of them.



So before making any decision, I just wanted to see if some people had a similar experience, and could share any thoughts from a job perspective.



In particular I'm wondering :


is there a big turnover in these types of position ?

can you manage a social life with this kind of day and night shift rotation ?

Is there opportunities as an expat to evolve from support in call center to network administration role in barcelona ?
does it require catalan or castilian ? 



thanks all
