Your decision quality and ability to make a quick analysis improves greatly over time and you become a seasoned interviewer.

You can speed things up by knowing what to look for ahead of time-- (skills, experience, motivation, cultural fit) and having a formalized candidate scorecard.

Use a stepped process where you either move an individual forward or eliminate them. First conversation via phone/Skype. 2nd conversation in-person at the office, meet the team. 3rd conversation-- meet for lunch/dinner. By this point you should know. Make a decision, don't drag it out.
