Brooks Utility Products interview questions

Applied in Indeed, interviewed face to face twice. They had me come in for a final interview and never heard from the company again. Not even an email stating they were declining me. Incredibly unprofessional considering I have interviewed face to face twice and took time out of my day to interview. They have gone thru 4 HR people in 3 years. So it that tells you anything that should be a good indication to stay away.
