What makes a deck look "senior" vs "junior" (it is not design skill)
I have watched people with average design skills put out decks that read as senior, and people with real talent put out decks that read as junior. The gap is almost never design ability. It is a handful of habits. Here are the ones that move a deck from junior to senior.
Titles that state the point, not the topic. Junior decks title a slide "Q3 Results." Senior decks title it "Q3 revenue beat plan by 12 percent." The senior version does the thinking for the reader.
One idea per slide. Junior decks cram three points on one slide to save space. Senior decks give each point room. A longer deck of simple slides reads as more confident than a short deck of crammed ones.
Restraint with color and font. Junior decks use five colors and three fonts because more feels richer. Senior decks use one accent color and a lot of white space. Restraint reads as control.
The ask comes early. Junior decks build to the point over twenty slides. Senior decks say what they want up front and spend the rest supporting it.
Nothing is there just to show effort. Junior decks keep slides in because someone worked hard on them. Senior decks cut anything that does not earn its place, even good work.
None of this needs talent. It needs the confidence to say less. That is the actual senior move.
