You have between 10-16 hours of time with a candidate depending on the desire ability of your job. I like to break it into: 1 hour of pitch/expectation setting where the only screening is for ability to complete the process (language, appropriate background, etc) and to catch obviously fraudulent candidates, 4 hours of take home technical assessment (programming project), 4 hours of soft skill assessment (3 hours of prep and 1 hour of presentation is my favorite format) and 1 hour of meeting with the hiring manager.

But, the format is not really the point. The point is to have a specific thing you are trying to discern from your filter and to focus your efforts on making that the only thing you are judging on.
