Candidates invest time and energy into interviews often taking time off work to attend.
People are understanding if they do not get the job.
But just rejecting someone without telling them any reasons why is really not on.
If you were to make an offer after an interview and an individual just said "its a no but im not going to tell you why its a no" you would understandably want to know the reasons and be a little annoyed at the lack of explanation.
So why wouldn’t you give individuals the same courtesy?
