People probably see these UX ‘immersive’ courses as the end-all and be-all because there are very few UX jr. positions, mentorships, and internships. UX designers are often seen as a solution to design, research, coding, etc. problems. Not a position you hire for growth. If the amount of people who tout their experiences and complain about the saturation of these certifications in the field took on mentees, interns, and jr. positions, there would be a change. Without that, I don’t see how spending 4k on a quick course to launch a career adds any value or diversity to UX.
