Sounds like mid-course time for Integrated Circuits 101.
This is where all that hard studying pays off.

Well, I guess you have three inputs and two outputs. Maybe you should
start by drawing a truth table?

Yep. Three inputs, two outputs.

The inputs:
- the job requirements,
- the interviewee,
- the interviewer,

The outputs:
- the street.

In your case, when we add the three input, you're immediatly carried to the
street output.

Well, of course I didn't mean your case, but Davy's case
