Work / 5 months looking for a job in PL and nothing! suggestions? [22]

I guess Comarch should be a good option for you - they are doing imlementation projects all over the world - also in Mexico :)
I think you need to contact right person to get proper iterview for you.
Try to contact this guy :
portel.de/nc/nachricht/artikel/40164-comarch-next-generation-network-p lanning/12/
(emails of comarch employees are quite easy to guess: <firstname.lastname>@comarch.com)

Good luck!
