What hiring process do you use?

What philosophy do you use when hiring new members for the team? The tendency for many teams is to create an interview hazing process.  Requiring interviewees to run a gauntlet of silly questions, riddles, etc.  Is it not obvious that this will result in a poor hiring decision? If you ask an experienced, knowledgable HR person they can tell you how poor the hiring process really is.  Ask a researcher and they will tell you that it is one of the poorest business process for producing the desired results.  Yet almost every organization continues this tried, but not true process. Google, being a big data company has done it's own research on the topic.  Read the results.

Estimation math made easy via zequals

How precise are your estimates?  Are we inferring false precision with those 5 significant digits?

Are those digits really necessary?  No.  Are they even real?  No.  They are just artifacts of inappropriate rounding or truncation.   There is very little doubt that someone could estimate a 4000 hour project down to the quarter of an hour (the implied accuracy of the 0.8 hour).  And if you think they are so good at estimating that they can distinguish between 45 hours and 50 hours for a portion of this project - well, then keep on trucking to the minute, or second.  There is a problem w
