Long hours and low pay doing repetitive tasks. At the contract employee level you will probably be given test plans that you execute over and over, not really free form bug hunting. But I have never worked on that side of things, and it probably varies considerably between organizations.
A digital input is much more realistic, one of the first things done when building a rally car is getting rid of the cable handbrake and replacing it with a hydraulic unit. For all intents and purposes, this makes it an on/off switch. Basically when you pull the handbrake in a real rally car it absolutely needs to lock the rear wheels in all scenarios, anything else is unacceptable.
That being said, lots of sim racers run analog handbrakes, but I would argue any situation you would need to drag on the brakes is better suited for left foot braking.
