The two worst captains I flew with were an older lifer and the Chief Pilot who did my FO IOE.

First leg of my IOE (DFW to DRO) he says he'll fly it because it's a high altitude airport. He proceeds to land about half way down the runway and bounces it 3 times, had to use max reverse and braking. Scared the **** out of me. He then misinterpreted radio calls twice and insisted he was right, forcing me to confirm with ATC. He was wrong both times.

He then had the nerve to tell me that he "Didn't think I was getting it." Thank God I finished my IOE with another senior LCA who was competent and gave me great marks.
