The Hiring Manager and Staff were all incredibly friendly and accommodating, which set a great tone for what the culture and workday environment would look like. However, after many weeks (7) and many phone and in-person interviews (including a four-hour session) I never heard back from anyone. I followed-up twice just to check-in, but received no response. I certainly understand if they chose another candidate, but I think it's a professional courtesy to at least let me know considering how far along the process I went-- not to mention the hours I had devoted to the interview process.
