The portfolio is the qualification
This is one of the few fields where what you can show outranks what you have
studied, at almost every level of employer.
That cuts both ways. Nobody will refuse to look at you for lacking a degree, and
nobody will forgive a thin portfolio because you have one. The work is the
argument, and building it is the actual job of your first year.
Fewer, better pieces
Almost every junior portfolio is too long.
Ten pieces where four are good reads as a designer with inconsistent judgement,
because an interviewer averages rather than takes the maximum. Four strong pieces
reads as someone who knows what good is. The second is a much better position and
it requires throwing away work you spent time on.
Print production is where reputations go
A design approved on screen and rejected at the press costs the client money and
you the relationship.
Wrong colour mode, images at screen resolution, live text in a font the printer
does not have, no bleed on an edge-to-edge layout. Four checks, and knowing them
separates a designer a studio keeps from one they stop giving print jobs to.
Learning to be argued with
The hardest part of the first year is not software.
It is presenting something you are pleased with, watching a client dislike it,
and responding by asking what specifically is not working rather than defending
it. Designers who never learn this do good work and are difficult to employ, and
they usually cannot see why the calls stopped coming.
