“Employers continue to push the boundaries with hiring practices, presenting candidates with obscure questions and challenges to test their thought process and problem solving aptitude. These questions and challenges rarely have right or wrong answers, rather employers are looking to understand candidates’ cognitive strengths, reactions under pressure and how they may fit into the existing team.”
