"Went through 4 + panel (5 people) interviews over 3-4 months All positive feedback and excitement both ways For the panel interview, I prepared an extensive presentation chock full of details, probably spending over 25+ hours on it. I got feedback that they all liked it, too, and requested that I send them the presentation, only to hear back that they were passing. I feel I worked for free, giving them all great ideas and, in some cases, how to implement them, only for this to happen."
