Applied online, received initial response within two weeks. Interviewed via telephone, multiple times, versus several panelists each occasion. Panelists varied from HR rep, program managers that Sr PM position would report to, and technical staff that Sr PM would supervise. Overall, the panel interviews were good.
Position would have required relocation to another city away from family, AND be on travel at least 3 weeks per month. Thus, the position required establishing a second residence that would be rarely used.
Biggest issue was past salary. HR seemed hung up on my past salary. When I declined to provide that information, the interview process stalled. (There is no state or federal requirement to share past salary information.)
Total duration of interview process 64 days, from resume submission to "thanks, no thanks" email.
