I agree with schlep. Basically, the best way to combat it is going to be practice and experience, to make the unknown feel more known. Start with a friendly situation, and gradually move closer to the real life ones.
Still, some skills are never going to be a comfortable fit. My husband finally told a boss that he had to stop bringing him in on certain sales calls. My husband is an engineer, not a salesman, and trying to hedge on engineering questions he isn't allowed to answer, just to make the potential customer feel good, isn't something he can do. Fortunately, the boss valued his other skills enough to agree to stop asking. Recognizing such limitations early on will help insure that the jobs are the best possible fit.
