Ask HN: Must a Senior Developer be proficient in design, UX and Photoshop too?

Had an interview for a Senior Developer position, they ask me if I have Photoshop in my Computer, also told me that I must be proficiency in CMS(Joomla, Wordpress, Drupal, ...) !!! That it is the definition of a Senior Developer, and the basic is to have these skills after think to do others things else. They also ask me how I'm going to manage a team with these skills if I don't know them well.
