Platform Computing Senior Marketing Manager interview questions

I was introduced to the hiring manager via email through a mutual acquaintance. The initial communication in mid-May was through email, followed by a phone interview in late May and a 1:1 interview in early June. Although I've pinged the hiring manager twice since then, it is now mid-July and I've not heard anything. I assume I am no longer being considered for the position, but it would be nice, and polite of them, to so inform me.
