Thanks for your reply. If this was a permanent position instead of a contract, it will be a lot easier for me as I'll have to go through the interview stage, and I don't think I'll have any issues with that. However it seems that for a contract position I cannot even get an interview and I think it's understandable: if you have to choose between two developers for a 3 months contract and both have a strong CV but one of the two has some examples of work to prove his skills/experience, I'd personally choose the one with the examples (assuming that they're good) instead of hiring/interviewing the other just basing myself on trust. So unfortunately I need source code to show.
