Seriously there is no need to worry much about what was required in the ad. The decision on which they will decide at the interviews will usually be decided on the persons they like rather than those mentioned abilites and skills. It is rather not on what they know or knew but rather what they have visibles. The rest can be trained. If you have these traits - a pleasant look or good-look for the job, a vocab skill to speak properly, the verbal skill to articulate well, a gracious manners to project a good image,etc. If these atrributes are found, they will bring forth $100K to the table.
