@Sans Souci I want to pass along a brief conversation my wife and I had not long ago that made me think of you.
No real advice here, just an observation that made me think.
My wife does most of the hiring in her organization and works hard to find the right person out of multiple applications and resumes she has to go through. She was sitting on the couch one night with three stacks of resumes, first the unread, then two sorted piles, a very small stack that will be followed up on and called for interviews, and a bigger stack that did not make the interview cut.
I asked her how she chooses who to interview and who to not persue further. Of course, the answer was not surprising, some who went in the no pile included ones with sloppy resumes, little relevant experience, or, more often than not, overqualified and doubtful to stick around for a long time as their resumes show they are agressively seeking advancement (something she can't offer a whole lot of), and those who seem to jump from job to job, not staying for much time at any one place.
I asked her what was the hardest part of the process and she said two things, one was there were some that she wanted to offer a job to because she felt they really needed it but were not really qualified, but the next thing she said is what surprised me. She said every time she did this, she always felt she may have made a mistake and felt that probably the best person for the job did not even get an interview, did not make it past the resume stage.
She said she always feels she may have not even interviewed the right person, that the best candidate, someone who would make a great, long-term dedicated employee she may have overlooked for whatever reason and it bugged her thinking that some small thing may have eliminated the best candidate, and she is the one who made the decision not to even interview.
She flat out said that she often thinks she may have eliminated the best choice without even knowing it and will never know what might have been had she not made the decision she did.
Sometimes things work out good for her and the organization with new hires, and sometimes she has to start all over to refill a position that she obviously did not hire the right person for, or they might have been the right choice but things changed in their life and they had to move on for whatever reason.
I think my point, if there is one, is sometimes people get overlooked for no known or real reason. Sometimes hiring managers make a mistake, sometimes they have lots of choices and have to decide based on something as simple as a misspelled word on a resume, misunderstanding the applicant's past work history, or simply feeling they move too often, or and she did tell me this too "Who knows, I might have found someone I think would be right and then I accidently put that person's resume in the wrong pile and never even get to meet them because I was careless while hastily trying to go through all these. Wouldn't it suck if I put the right person's resume in the wrong pile?"
I asked her if she thought she had ever done that? She said "It's possible."
