"Self disclosure is the process of deliberately revealing information about onself that is significant and that would be normaly known by others"
In short, self-disclosure is ....sharing information with others that, they would not normally know or discover.
CareerMakers, a professional human resource company that provides seminars for job interviews, graduates reports that learning to tell stories in job interviews is one of the most practical and powerful skills they learn at CareerMakers. Stories have contributed to their success in becoming known to their interviewer (self disclose) and boost up their confidence. During in an interview, the interviewers would asks repeatedly "give me an example of when you have written your company newsletter?". Meaning that, the interveiwer wants you to disclose yourself about your success in your preveious job. "Example = successful stories". They would also asks for specific names, skillls and results as a confirmation that once you have done it successfully in the past, undoubtedly, you can repeat the success again in the future. Events from your life will determine whether or not you have the skills to do the job. Now,what they are trying to say here is, some of us think that we are articulate when we use phrases like "I'm good with people" or " I'm a hardworker" in an interview. The problem with theess statement is that it doesnt come with life events and doesnt come with concrete information that illustrates the skills or trait that proves our claims. All these are disclosed so that the interviewers will have full confidence in us. We disclose our past events to the interviewers.
