It’s important to know what a company’s procedure is, as much as you can tell or find out, and to understand generally how the process works today perhaps as compared the last time you looked for a job. It is more automated, more technology driven, more key word intensive and, right or wrong, less personal. At least until you make it into the smaller group that is selected for interviews or phone screens.
Employers determine the process they will use to fill their positions. The more you can find out about their rules, the more successfully you can play their game.
