I had high hopes from the start. But, frankly, I think you missed hitting the nail on the head. The title of your blog is for Companies and Candidates? And this is where you set the base and fall short, in my opinion.
Candidates are individuals and you refer to them as such. But companies? Companies don't conduct interviews. The company does not decide. A company is just a legal entity. It is lifeless. It's the individuals that are employed "by" the company who are alive and active. And as such they should be address.
I know, "companies" are your clients. They are the one who pay you at the end of the day and hence you want to be nice to them, and in doing so you fall short. You're suggestions will probably fall on death ears because those who care enough, don't do, and those who don't - don't even care what you think. It reminded me something I heard at Motorola some 15 years ago when I asked about the evolution of design methodologies. The answer was "we don't change methodologies when we are in a project, and when we are not in a project we don't care". And on that basis let me share with you what I think you should have written.
When you are interviewing a candidate, a little humility will go a long way. And please, leave your ego outside of the room. It's a lot to ask, but you yourself gave several examples for "this is how we do it" which also spells " we know best", and under that method of thinking you also will find (and these are not oddities):
- the executive who will talk to a candidate while he's constantly checking his e-mails.
- the person who walks into the room to interview a candidate and admits he just got your resume and he has no idea what you're here for. And that is after you've been waiting in the lobby for 30 minutes after your scheduled appointment, and you were not the only one...
- the person who knowingly or unknowingly will exhibit biggotry, prejudice, stereotypical thinking and ignorance to blatantly violate every chapter in the EEO laws. But would you really want to work with him? (you mentioned foreigners as interviewees, and went on about understanding them. Brother, you seems to have forgotten these foreigners may also be conducting these interviews)
- the person who asks you a question and you realize that even he does not know the answer and he's just fishing for a solution to solve his current problem in the project.
- the person who asks you a question and you realize that the position for which you came for this interview has been "slightly" modified ...and no one even bothered to inform you.
You see, when you are on the interviewer side, it's very easy to take on the high and mighty, even condescending approach. As " You are now at my mercy". But ones forget the basic "Do unto others as you would have others do unto you." If you look at the ever growing graveyard of companies that once were and are no more, the table can very easily be turned around.
