The answer to your good candidate question is entirely dependent on each specific job. Academic vs. private vs. corporate may have different things they're looking for. Regarding private groups, recently I have seen examples of a group wanting younger pathologists just out of fellowship and other groups want someone with experience. One group might prefer a man and another might prefer a woman for some particular job.
My advice is try to work on what you can control, such as your training, your competence and your demeanor. Those offering a job in pathology can be very particular about who they want. As I'm sure you've figured out, that means lots of effort (and perhaps some luck) on your part.
