It is easier, and better for our egos, to enter a new job and begin making major changes, than it is to learn the history, state and proper care of what exists. Premature decisions like this can be damaging for a company. Try to take ample time to learn first.
Hiring managers often have to sort through dozens of applications. This is overwhelming and can lead to arbitrary rejections just to lighten their load. Another reason not to take rejections personally.
One thing I've learned: bad recruiting software (application process collaboration tools) makes it easy to lose resumes. If you don't hear back, that could be why.
@flexyford Interesting. I'd argue that the recruiting tools a company uses reflect their internal values, and if they rely on a parser to force a resume into their format it's a count against them
