Hello, I will be graduating college in about two months and am practically clueless as to what to wear. I'll be applying for jobs at engineering firms but my field of study is broad so I could end up working in mostly any industry. Is the black suit with a tie an interview staple? I prefer a navy suit but I don't know if this is too informal. The only pair of "nice" shoes I own are a pair of Allen Edmonds Strand's in walnut but I feel that these are a little too flashy for an interview. Can someone recommend me some footwear to go with my suit assuming the suit is the standard of interviews? Thank you.
