I was contacted by a recruiter a short while ago asking my availability for a phone screen- and I replied simply with my availability. The recruiter still hasn't gotten back to me, and I think that it may be because I didn't go out of my way to thank them for reaching out to me.
Are all of the niceties in your email inbox really that important to people? It seems pretty manufactured and boilerplate when people send me emails that they "hope find me well".
I may just have to get over it and start letting people know how "excited I am to speak with you and learn more about this opportunity!"
