Lots of real phenomena occur during an interview. For example, you could go one level deeper and describe the molecular mechanisms between adrenaline and whatever 'receives' adrenaline. That would sound something like:

"What happens in job interview is that adrenaline binds to a variety of adrenergic receptors, which triggers a number of metabolic changes" [1]

It'd be just as real, also clearly connected, but also quite clearly not what the conversation is about.
