Also game companies typically dont want a web link to your stuff, they want a hard copy, along with source code etc. if you look on EA they say any portfolio hosted on the web will be ignored, due to safety reasons or something.
also in relation to what mal said about being too busy working on the companies game, i would imagine that isvery true. I can only speak from my own experience of working a 8-5 programming job (non game related, so i suspect game related in much worse) 5 days a week, do you not find your wrecked tired, just want to kick back on the couch and\or possibly sleep. im still amazed where people find the hours to develop really high class games in their spare time, on their own. Although i will say more power to them.
