I applied online after seeing a job post. Application required a resume but no cover letter and used an extensive questionnaire instead. I actually liked this because I felt it gave me a better sense of what they were looking for. I got a phone call within a few days but missed it. I was not going to be moved forward because I did not have a private investigator certification, which takes several months. This is disappointing, because apparently this is a location-specific thing and that is not specified in the job description (explicitly stating which locations were eligible would have been helpful!). I emailed in the hopes I could get more feedback/maybe set up a call time, but the same person left me a message with the same information for why I was rejected. I respect that there is only so much that an applicant can learn/why more detailed feedback can't be granted but it is extremely discouraging that this has to be a barrier for even an interview, especially when comparing the cost for certification compared to the stated salary. The bare minimum the company could do is list where applicants are/are not eligible for hire based on requirements. It will save everyone some time.
