Extremely long interview process. Five months from initial contact to offer. Phone screen, additional phone screen, in-person, three panel, then a final in-person. I followed up after each phase a day or two after then waited another week to follow up with HR again. Typically, I would get a response from quickly after the second follow up. However, my contact person switched maybe four different times? Extremely unorganized in the interviewing process and I don't belive the hiring manager knew exactly what they were looking for.
