At Mission Critical Psychological Services, we have refined our ability to identify the personality profiles that are successful in hostile environments through nearly 10,000 face-to-face candidate interviews. We offer two levels of screening for assessing candidates' psychological fitness for duty: the online Hostile Mission Assessment and the face-to-face Hostile Mission Evaluation. Before reviewing candidates, we gain a thorough understanding of the working conditions, expectations, potential problems, and challenges of the positions for which candidates are interviewing. We also provide Hostile Mission Readiness Training as part of our pre-mission orientation programs.
