Companies increasingly want employees to be trained all-round. Nowadays it is expected that marketing and communication employees can also work with graphic design programs and even design a bit themselves. Preferably for online media and for print media as well.
I believe that everyone can get along with the well-known Adobe or Affinity programs, if it is clearly explained and the time is taken to acquire the knowledge. That is especially the case with someone who guides the student for a few weeks and is available to answer questions. The in-company package creates more depth than in the other courses, mainly because it is a longer process. This means that a course does not have to be learned in one day, but a course for a program can contain several days.
