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.

STEPS IN THE SELECTION PROCESS
The selection process typically begins with the preliminary interview; next, candidates complete the application for employment. They progress through a series of selection tests, the employment interview, and reference and background checks. The successful applicant receives a company physical examination and is employed if the results are satisfactory. Several external and internal factors impact the selection process, and the manager must take them into account in making selection decisions. Typically selection process consists of the following steps but it is not necessary that all organization go through all these steps as per requirement of the organization some steps can be skipped while performing the selection process.
1. Initial Screening
2. Application Blank
3. Pre-employment Testing
. General Intelligence Tests
. Aptitude Tests
. Personality and Interest Tests
. Achievement Tests
. Honesty Tests
4. Interview
. Structured Interview
. Unstructured Interview
. Mixed Interview
5. Background Checks
6. Conditional job offer
7. Medical Exam/Drug Tests
8. Final Selection Decision

Binary Exponential Backoff Algorithm was chosen to dynamically adapt to the number of stations trying to send. If the randomization interval for all collision was 1023 slots, the chance of two stations colliding for a second time  would be negligible, but the average wait after a collision would be hundreds of slot times, introducing significant delay. On the other hand, if each station always delayed for either 0 or 1 slot, then if 100 stations ever tried to send at once, they would collide over and over until 99 of them picked 1 and the remaining station picked 0. This may take years. But having the randomization interval grow exponentially as more and more consecutive collisions occur, the algorithm ensures a low delay when only a few stations collide but also ensures that the collision is resolved in a reasonable interval when many stations collide. Truncating the backoff at 1023 keeps the bound from growing too large.

100 means 100 bps (bits per second). This is the data transfer speed for cables.

A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational databasean index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index. Another option sometimes supported is the use of "filtered" indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.
