You're not going to be accountable for the five-year question; it's important to demonstrate a direction is all. You'll find something more interesting along the way; the plan just keeps you moving in *A* direction.
I don't have any offhand, but the takeaway for me is that interviews are always two way streets. It's not about "passing / failing," it's about determining mutual fit.
If a company treats you like crap in the interview, why would you want to work there?
"They agreed not to pursue charges if I left quietly" is on the spectrum of terrible answers.
"You do a lot of X, you won't be able to do that here" for most values of X are great examples.
"Yes, I dabble in functional programming. Slight change of topic, your company paid how much last year in severance payments to get rid of Sexual Harassment Panda VPs?"
"Yes, I read your job req. The only person who would is basically @kelseyhightower if he tripped and fell into a time warp."
What the answer says is that they'll need to provide a growth path for you, or you'll find one elsewhere. That's a fair employee expectation.
I’d answer the question that way and assume they’d bungled the framing. If they dig further into personal stuff, fuck that place.
