People like to brag. If someone says "this took us a weekend to put together", I generally expect (for example) all the planning was already done, a code skeleton was already put together, etc... Any time someone says "oh here's a little project I put together in a weekend" your "bragging" detector should be quietly blinking, which signals to you the claims are likely at least a little inflated.
