I have done some interviewing and such of candidates at my current place. I sincerely could not imagine asking a candidate with a job to spend three trial days (or a single day) coding with us. I think it's disrespectful. Not everyone who is looking for work is unhappy where they are. I don't want to put anyone in a position where they have to choose between respecting their current employer and seeing if they're a good fit with us.
