Abstract: Technology is described for determining a candidate's suitability for a work profile. The method can include identifying a candidate's abilities by obtaining the candidate's electronic response to a plurality of problems presented in a work simulation. Another operation may be capturing a candidate EEG (Electroencephalogram) during an electronic response provided by the candidate. A normal neuro-mappings for the plurality of problems may be obtained based in part on aggregated EEG data for a group of individuals for the plurality of problems solved in the work simulation. The candidate EEGs for the plurality of problems can be compared to the normal neuro-mappings for the plurality of problems. Candidates may be scored based in part on the amount candidate EEGs diverge from the normal neuro-mappings.
