"And this is what most people get wrong: They think a 'buffet résumé' is the best way to go."  Nicolai says a buffet résumé is one that has too much going on ... one that offers too much information.  "My clients often think a résumé that is a smorgasbord is best because it demonstrates the bandwidth of skills, experiences, and achievements that they have in their repertoire of success," she says.
