I've been interviewing for a project manager position with a retailer that has several hundred stores throughout the US and overseas. The process started as an initial phone screen with their corporate recruiter. Since then, I've met 1:1 with the CEO, Head of International Sales and the Head of HR. I was also recently invited to come back in for a (2-hour) face-to-face interview with their Head of Retail Operations. What I noticed this time around is that all my communications for interviews are now going thru the Head of HR. I'm taking this as a good sign if she's taking over from the corporate recruiter. I can't imagine the Head of HR being involved in something so mundane as scheduling interviews if they weren't more than a little interested in me on some level. If it helps, the position will report directly to either the CEO or the Head of Retail Operations. Any thoughts?
