3 rounds were there the hr round one with the reporting manager and finalwith the senior management it was ok overall and well suited for the position i was applying for

Had a great 1st and 2nd interview with the next step to have a 3rd at their HQ. They completely went dark without the courtesy of closing the loop. Extremely unprofessional and inconsiderate- Not only that they asked for references and my last 2 paychecks. That's rather personal for it to not progress. I feel like they used me for information-
