The pieces of information list below may be common and even sometimes required in some countries. Including such information should not hurt you, but we recommend avoiding it regardless if you are applying for companies in such regions as North America and Western Europe.
Why? Such pieces of information increase the probability of biased or simply unfair decision making and we believe good universities, employers, and countries discourage from including it.
In the ideal world, it should not matter, but if you include this information we believe it may send a small unconscious signal that you are not aware of such potential biases and unfair treatment at a workplace.
We recommend excluding:
Date of birth
Number of children
