This paper presents the results of the Virtual Internship project that aims to help young job seekers get insights of different workplaces via immersive and interactive experiences. We designed a concept of `Immersive Job Taste' that provides a rich presentation of occupations with elements of workplace training, targeting a specific group of young job seekers, including high-school students and unemployed. We developed several scenarios and applied different virtual and augmented reality concepts to build prototypes for different types of devices. The intermediary and the final versions of the prototypes were evaluated by several groups of primary users and experts, including over 70 young job seekers and high school students and over 45 various professionals and experts. The data were collected using questionnaires and interviews. The results indicate a generally very positive attitude towards the concept of immersive job taste, although with significant differences between job seekers and experts. The prototype developed for room-scale virtual reality with controllers was generally evaluated better than those including cardboard with 360 videos or with animated 3D graphics and augmented reality glasses. In the paper, we discuss several aspects, such as the potential of immersive technologies for career guidance, fighting youth unemployment by better informing the young job seekers, and various practical and technology considerations.
