Selection Process

Selection is the process of choosing from a group of applicants those individuals best suited for a particular
position. Most managers recognize that employee selection is one of their most difficult, and most important,
business decisions. This process involves making a judgment -not about the applicant, but about the fit
between the applicant and the job by considering knowledge, skills and abilities and other characteristics required to perform the job Selection procedures are not carried out through standard pattern and steps in this. Process can vary from organization to organization some steps performed and considered important by one organization can be skipped by other organization.
Environmental Factors Affecting the Selection Process A permanent, standardized screening process could greatly simplify the selection process. However, development of such a process even if it were possible and desirable would not eliminate deviations to meet the unique needs of  particular situation.

Legal Considerations
Legislation, executive orders, and court decisions have a major impact on human resource management. It is important for hiring managers to see the relationship between useful and legally defensible selection tools.

Speed of Decision Making
The time available to make the selection decision can have a major effect on the selection process. Closely following selection policies and procedures can provide greater protection against legal problems; however, there are times when the pressure of business will dictate that exceptions be made.

Organizational Hierarchy
Different approaches to selection are generally taken for filling positions at different levels in the organization.

Applicant Pool
The number of applicants for a particular job can also affect the selection process. The process can be truly
selective only if there are several qualified applicants for a particular position. The number of people hired for a particular job compared to the individuals in the applicant pool is often expressed as a selection ratio.

Type of Organization
The sector of the economy in which individuals are to be employed private,  governmental, or not-forprofit can also affect the selection process.

Probationary Period
Many firms use a probationary period that permits evaluating an employee's ability based on performance. This may be either a substitute for certain phases of the selection process or a check on the validity of the process.

Selection Criteria
Mostly the selection of applicant depends upon the
following factors or criterions.
1. EDUCATION
2. COMPETENCIES
3. EXPERIENCE
4. SKILLS AND ABILITIES
5. PERSONAL CHARACTERISTICS

Applicant who is best fit should be hired instead of hiring a person with extra ordinary skills it means right person for right job should be hired person who is over or under qualified for the particular job will not be able to adjust in the organization.

Virtual destructors: If an object (with a non-virtual destructor) is destroyed explicitly by applying the delete operator to a base-class pointer to the object, the base-class destructor function (matching the pointer type) is called on the object.   There is a simple solution to this problem - declare a virtual base-class destructor. This makes all derived-class destructors virtual even though they don't have the same name as the base-class destructor. Now, if the object in the hierarchy is destroyed explicitly by applying the delete operator to a base-class pointer to a derived-class object, the destructor for the appropriate class is called. Virtual constructor: Constructors cannot be virtual. Declaring a constructor as a virtual function is a syntax error.
