Unemployment has long been considered a risk factor for mental health. While jobsearch is an extremely draining and stressful process, the job-search systems thatjobseekers use do not have to be. Among the many pressuring factors that are known tocontribute to stress, it remains unexplored how job search systems UX impactsjobseekers. This study aimed at identifying and understanding job search systemsrelated stressors based on existing stressor characteristics and on stressless designheuristics. To achieve this goal, semi-structured interviews were conducted incombination with a survey. Thematic analysis was performed to identify themes; and asurvey was conducted to gather the broader sentiment on job search experience.The results show that existing stressless design heuristics are effective in thinkingdesign for stress; as new themes emerged, three new heuristics are proposed.The 3 main stressors identified are related to poor UX in terms of feedback systems,complex interactions to fill in application forms, poor job description quality combinedwith a wanting job search capability. The major reasoning for the identified stressors isthat they are perceived as hindrances towards the main goal – getting a job.Stressor’s impact appears in the form of lowering job search engagement and makingjobseekers develop a negative attitude towards online job search.One important finding is that these stressors only become visible over time; this mighthave an implication on how software is tested and evaluated for stress. The findingswere discussed in view of previous studies, practical and scientific implications arepresented as well as suggestions for future research.
