Had an initial HR phone screen, initial manager interview, took a timed test, follow-up with hiring manager. Three more interviews with team members, 2 of 3 seemed disinterested in their jobs and generally unfriendly. One of them (who would not even deal directly with this position) seemed particularly hostile, firing off questions like he was R. Lee Ermey. Questions were strange, mostly standard behavioral questions rather than getting to know me. HR ghosted after all that, totally unprofessional for taking so much of my time to not even email me a generic "no."
