Imprivata Director, Marketing Operations interview questions

Contacted by recruiter then put in touch with HR; phone screen with HR went glowingly and immediately scheduled phone interview with hiring manager, VP of Marketing. The phone conversation with hiring manager was less than ideal. Without the advantage of face to face engagement, the typical phone call challenges were faced; we spoke at the same time, there were silences, background office noises, etc. When we ended the call, I didn't expect an invitation to come in; I was right---which is fine. However, there was no feedback or closing of the loop by HR---which is disappointing, as I believe that's basic professional courtesy. Two months later and the role still isn't filled, so suspect I'm not the only one that struggled with the phone interview portion of the hiring manager. Would suggest given his style, accent, etc., perhaps face to face interviews should be considered; and certainly recommend closing the loop with candidates regardless of outcome.
