When we speak of software design, we often refer to 'UX design'. The job market is flooded with vacancies for UX designers. In fact, the larger part of my LinkedIn profile states that I'm a UX designer. I actually think this is wrong. Or, outdated at least.
UX - and UI design are often mixed up or considered one and the same thing. We see this in recruitment all the time. Whether that's due to a lack of understanding, or because designers are required to be proficient at both: they're really not the same.
