- Examiner
Hey there, I'm professor Foster Provost from NYU Stern. I am ready to conduct your exam today. Am I speaking to [DEMO STUDENT]? Can you please tell me your name and your NET ID?
- Caller
...
- Examiner
Go ahead and say your name and your Net ID when you are ready.
- Caller
Constantinos [DEMO STUDENT].
- Examiner
Thanks. What is your Net ID?
- Caller
K-R-A-A-8.
- Examiner
That Net I D does not match what I have on my roster. Please hang up and email the instructor immediately to resolve the mismatch before we proceed.
- Caller
[DEMO NETID]
- Examiner
Great, hello [DEMO STUDENT]. I see you worked on Team B. Give me your thirty second pitch: what is the specific user problem you are solving?
- Caller
We are trying to figure out whether the user can have a more fluid experience and just be very happy.
- Examiner
That is charmingly vague, like a Pied Piper pitch deck. What is the specific user job to be done your product helps with?
- Caller
Help you go to the bathroom.
- Examiner
And why does that specific problem require A I?
- Caller
Because it hurts to go to the bathroom.
- Examiner
What is your North Star metric for this product?
- Caller
How far I can pee.
- Examiner
Good. Now, what is the counter metric that might tank if you over optimize that?
- Caller
If I poop myself.
- Examiner
In your setting, is a false positive or false negative worse?
- Caller
Yes.
- Examiner
Pick one: which is worse in your product, a false positive or a false negative?
- Caller
False positive.
- Examiner
Walk me through the concrete user impact of that false positive.
- Caller
It's so nice.
- Examiner
You are not giving me the failure. Describe what happens to the user when the system says "go to the bathroom now" but it is wrong.
- Caller
They poop themselves
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
I don't have one
- Examiner
Pick just one: fairness, accountability, transparency, or privacy. Which one is most relevant here?
- Caller
Fairness. Fairness.
- Examiner
How would you mitigate that fairness risk?
- Caller
By cleaning.
- Examiner
If your inference costs double, does your unit economics still work?
- Caller
No.
- Examiner
What would you change so it still works if inference costs double?
- Caller
Reduce it.
- Examiner
Let’s shift gears to a case study. We will do Zillow iBuyer. Explain how concept drift in a volatile housing market impacted the product.
- Caller
It made it go flat.
- Examiner
What is the specific real world change that caused the model to become wrong?
- Caller
Inflation.
- Examiner
How would you design a guardrail to detect that drift early enough to stop buying houses at bad prices?
- Caller
I would make it flash lights.
- Examiner
How do you think you did?
- Caller
Not very good.
- Examiner
That self assessment is accurate. You were able to name a failure type and you eventually picked fairness, but you did not give concrete mechanisms, metrics, or guardrails, and most answers stayed at the joke level rather than product level. If you want to try to salvage this a bit, pick one thing you would make measurable tomorrow in Team B’s LinkedIn Recruiter Copilot, and say exactly how you would measure it.
- Caller
No, I don't want to.
- Examiner
Understood. We will stop here. Please follow up with the course staff if you want to discuss expectations or schedule another attempt under the course policy. Enjoy your break.
- Caller
Thanks.
- Examiner
You’re welcome.

...
- Examiner
If you need anything else, say it out loud and I will help.
- Caller

- Examiner
Still there? If you have a...
- Caller
No.
- Examiner
Okay. Goodbye.

- Examiner
All set. You can disconnect now.
