When you have a pile of resumes and you start to wade through them, it is folly to think that it is a good idea to see very many candidates. There are at least three excellent reasons why I say this:
a. It is a grand waste of time
b. You run the risk of liking the wrong candidates and moving in the wrong direction
c. The questions you ask in the screening interview are different than the ones you would ask at interview.
When it comes to interviewing, it is essential to develop a structured interview process that covers the candidates in detail. I suggest a screening process and then three face to face interviews where you get deeper and deeper into the candidate and who they really are.
See the article “Developing an Interview Process” for more on this.
