This thesis deals with one of the most debated topics of the Personnel Psychology - the personnel selection. The aim of the thesis is to provide an exhaustive overview of the designing process of the selection procedures with special attention being paid to the various methods of selecting employees. Attention was primarily paid to the effort that the knowledge of the otherwise common methods of selecting employees be put in the new framework and the latest ways of their application. Particular emphasis has been put upon the new approaches to the method of interview, cognitive abilities testing, detection of individual personality at work and new methods in designing assessment centers. An interesting chapter is the use of emotional factors as selection criteria and the application of the attachment theory to work. Considerable extent of the thesis is also devoted to the methods of job analysis and competency modeling, their comparison and applications. Based on the previous theoretical treatise the empirical part attempts at creating a competency model for senior executives in the hotel industry and proposes possible ways of its practical use.
