You ask the following: In what reasonable time period should institutions/individuals inform the interviewee of the outcome?
To my understanding, there is no standard to be followed in this case. When a perform research that involves the participation of interviewees, I inform them as soon as I finish my research and have findings to report.
Thanks Orlando M Lourenço . I mean when one is interviewed for a job. What time must it take before one gets a response of having gotten the job or not? For me it borders on emotional abuse if an employer does not come back to you as soon as possible
You are right while saying that it borders on emotional abuse if an employer does not come back to the candidate as soon as possible. As you know, we live in an unjust world.
