When a potential employer doesn't tell you the name of the company, that's fishy. When a potential employer gets back to you with one word answers and doesn't actually give you any details, fishy. When the potential employer replies in a manner that suggests they know what they are doing, when they really don't (ex. don't even give me the address I am supposed to go to....hello...), it seems fishy and incompetent.
Sounds like a dead fish to me.
I HATE being led on.
