Solid State Devices interview questions

Multiple days, with multiple people from technical, sales, manufacturing, quality and management groups. General questions about the semiconductor devices such as PNP, NPN, Schottky, Pch MOS, Nch MOS, rectifiers, zener devices, assembly process, test methods.

Started off nicely and ended weird. Went there twice and even met the owner, he said he would send me something and then never heard back from them. Followed up then randomly one day one of their managers called me and started talking to me like it was beginning of the process again. I told him I had already gone thru a lot of these questions before. I think he was mistaking me for someone else or something. Anyway i didnt make a big deal but didnt really follow up Hate disorganized companies that dont communicate with each other. Also what happened to most basic courtesy of following up? Even if you don't get the job usually they let you know soon but i heard nothing from these guys.
