This company & its personnel director while perhaps "highly professional" by some nonetheless are "out-to-lunch" when it comes to consideration of applicants.
I considered applying yet noted the identity of the NPO's ad was not revealed. Seemed strange since I'm not inclined to go thru an application process, especially with what I read in reviews is extensive and demanding, w/out knowing the identity of the organization given I may simply not want to support it.
Called getting someone who said she was the personnel manager & on asking of the identity of the organization in question, she said in no uncertain terms they don't reveal it. I noted how that policy is not considerate of applicants compelled to devote significant time, effort & possibly costs w/out knowing the entity they are applying to. Made no difference to her. Asked to speak w/her superior to no avail.
