information provided by the application form is insufficient. The information provided by the application form needs to be further proved. There are at least two probabilities that will influence the reliability. One is whether all the information of the forms is true. Evidently, not all applicants are honest. It is possible that the information was magnified, omitted or even not existed. The other is whether the selector misunderstands the information of the form. Because the selection only based on the data without confirmed, then the selectors use some models or logic make some conclusions.

On one hand, the selector cannot let the applicants to clarify whether the selector has misunderstood them; on the other hand, some applicants know nothing about the organization. They argue: "I have that ability, but I just don’t know they want to know that. If only they give me a chance to explain…" cannot feedback is an unmistakably shortage of application form for both sides.It is a heavy job for file work. Generally, application form provides maximum applicants. Some books, therefore, argued that the application form provided sufficient candidates. It was an advantage. However, if the organization puts its advertisement in a right media for other selection methods, it will attract enough applicants too. What they lack to consider is, the application form also provides more inappropriate applicants than any other selection methods do. Evaluate them and subsequent administration becomes a heavy task.CONCLUSIONEach method has its strengths and weaknesses. No one is perfect. So, the best way for selection is that the two methods combined together to use their strengths and limited their weaknesses. For example, interview has low validity and reliability but if use it in association with biographical information (from the application form) may increase both of them. ...
