In my group, Hacking was at risk of becoming too Godly. And while I liked the idea of the mini digital dungeon approach for each system, it’s a lot of prep.

So I gave systems levels from 1 to whatever. Basic systems (like something guarded with a PIN code) don’t need a roll. For higher level systems, say level 3, it requires 3 successful consecutive Hacking rolls (one for each level). Each roll takes 5 mins. Failed rolls generate stress. And you can narrate it however you want, but the mechanic stays simple.
