The second suit could be tailored into adequacy. But it's not for an interview (usually that should be dark gray or navy and single-breasted). This is kind of a case report on why a style 'noob' shouldn't do much important thrift shopping.
If it weren't so short, it would be nice-looking. However, for that kind of money (probably too much) in NYC or Boston (as claimed in the other thread), better to get a longer, warmer, different kind of jacket (or coat) altogether.
Go slow is solid advice. But "buy custom" and that link hardly help.
Size information/measurements and a location would help.
The "cool black coat" might refer to an overcoat, but black is not a good choice for that or much other clothing. (The main piece of dressy outerwear usually should be navy or dark gray.)
Overcoat choice partially should be based on body type. Little point in trying to explain it all when measurements would make an answer easier.
Whole-cuts for a junior employee - probably not a good idea and surely wrong for interviewing.
