[Excerpt] Talent Acquisition departments are the frontline soldiers in the war for talent. Selection tests and simulations are common mechanisms by which firm’s filter through potential job candidates. Nevertheless, a 2017 Deloitte survey reported that 71% of firms believed they were weak in their ability to use these tools effectively. Using assessments is a balancing act between false positives (hiring the wrong candidate) and false negatives (rejecting the right candidate). As such it is important to understand the benefits and pitfalls. This is especially true with technical assessments for coders and programmers.
