Initially described by their Talent Aquisition person (Mark) as four rounds, it kept changing. After screening with Mark, I interviewed with hiring manager, which went well enough that I then interviewed with two of his direct reports (north american sales leader and then rest of world sales leader). All went well (to me). Then ghosted. NO response to emails asking for followup. Will NOT work for a company like this. I know everyone is "busy" but a simple acknowledgement or a polite "no" is not too much to ask.
