I interviewed with a new principle that had no interview etiquette. First question was about my background in project management and BIM management. Second question was how much is my salary requirements. From my experience, this is a red flag and means they are trying to recruit some affordable low qualified talent. This means if you give them the low ball number they are looking for they will offer you an in person interview. This is how I screen the seasoned firms that are willing to listen to the value and experience you can bring to the table vs. the firms that are just looking for affordable low level employees.
