Thanks for the reply Bleeding Red. And you raise a good point about a lot of unqualified resumes showing up in a posting. I have seen that when I was involved in selecting candidates for interviews. All I can speak to is my own practice, which is that I only send in my resume for jobs I am qualified for and capable of. Also thanks for the examples of researching. I also prefer the algorithm to HR folks.
tvp2003, I remain convinced that a big part of getting selected and hired is timing. Luck has a some to do with it, but it's definitely not the single factor.
