If players don't know Netrunner, the best format is a faceup draft, like Grid or Rochester Draft. So that they can see all the cards and know what they do. This does take away elements of the bluff game that goes into Netrunner Corp, but we're doing this for the sake of new players, so I'm ok with it.
In case you don't know, here's the rules for Rochester/Grid. (There's other formats as well, I think Winchester and Solomon are the faceup ones. I keep confusing Winchester and Winston draft formats though...)
Rochester Draft. Build the packs normally, but only open one at a time, and display all the cards on the table faceup. Each players picks one card in Horseshoe order. (Four players: A, B, C, D, D, C, B, A, A, B, C, D, D... etc) until the cards are gone. Next player opens their pack and repeat the process. (A opened first pack, so B opens his first pack and start the Horseshoe with B.)
Pros: Everyone sees every card. Every card is drafted. Equal number of cards in each player's pool. Works with any number of players.
Cons: Everyone sees every card. Takes a long time, relatively. No mystery of what other people are drafting. The 'wheel' position of the horseshoe can be unduly powerful.
For only two players. Make nine-card packs, and then open each pack in turn, displaying them face up in a 3x3 grid formation. In turn, each player picks either a column or a row. Swap player order each pack.
Variant: You can try getting a third player in on this, giving them the 'leftover' after the first two have picked. Rotate the player order with each pack. I'm not sure this is good, but it exists as an option to try and add players to this format.
Pros: Everyone sees every card. Not every card is used. Quick draft format for two players.
Cons: Only works perfectly with two players. Possibility of unequal amount of cards in each player's pool. Due to card layout, can prevent certain strategies from being viable.
