- 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 NetID for me.
- Caller
Hi.
- Examiner
...
- Caller
I'm just Drain Count, the AI agent.
- Examiner
Tell me your NetID.
- Caller
Hi
- Examiner
State your name and NetID.
- Caller
Hey
- Examiner
Please state your name and your NetID.
- Caller
. Can you hear me?
- Examiner
Yes, I can hear you. Please state your name and your NetID.
- Caller
...
- Examiner
...
- Caller
[DEMO STUDENT] as the name and [DEMO NETID] as the net id
- 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
...
- Examiner
Go ahead and give me your thirty second pitch: what is the specific user problem you are solving?
- Caller
Well, I was solving this problem of not being able to click on the menu.
- Examiner
And why does that specific problem require A I?
- Caller
...
- Examiner
And why does that specific problem require A I?
- Caller
...
- Examiner
Are...
- Caller
Because, yeah.
- Examiner
What is your North St...
- Caller
Because... Sorry?
- Examiner
And why does that specific problem require A I?
- Caller
Because humans would have to invest a lot of time to resolve this issue, but AI can do it faster.
- Examiner
What is your North Star metric for this product?
- Caller
What does it mean?
- Examiner
What is your North Star metric for this product?
- Caller
Yeah. What does a North Star metric mean?
- Examiner
It means the single most important measurable outcome you optimize for that best captures whether the product is delivering real value over time, like sustained usage or retention rather than a one off click. Now answer the question: what is your North Star metric for this product?
- Caller
It's whether the users on the end can go through the menu easily.
- Examiner
Give me a number: how would you measure that, specifically, in the product?
- Caller
Well, it's the number of clicks that they have to use to go to the area that they want to go.
- Examiner
Good. Now, what is the counter metric that might tank if you over optimize that?
- Caller
Once again?
- Examiner
Good. Now, what...
- Caller
Please...
- Examiner
Good. Now, what is the counter metric that might tank if you over optimize that?
- Caller
...
- Examiner
Take a moment and give me one counter metric.
- Caller
...
- Examiner
If you need a second to think, say so. Otherwise, give me one counter metric.
- Caller
Yeah I need a second.
- Caller
Yeah it's the number of users that they quit the app before they even get to where they want to go.
- Examiner
Good. In your setting, is a false positive or a false negative worse?
- Caller
...
- Examiner
In your setting, is a false positive or a false...
- Caller
Yeah I need a second to think please.
- Caller
I would say a false positive.
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
No idea.
- Examiner
Pick one concrete scenario where your system wrongly flags a menu issue when there is not one, and tell me what the user experiences.
- Caller
Well, the user is gonna be asked
- Examiner
Finish...
- Caller
whether they experienced the issue and what is happening.
- Examiner
Pick one F A T ...
- Caller
So it could be
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
... What?
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
What is an FAP issue?
- Examiner
F A T P stands for Fairness, Accountability, Transparency, and Privacy. Now pick one F A T P issue relevant to your domain.
- Caller
It's the leak of the personal information of the users.
- Examiner
How would you mitigate that?
- Caller
I would set a system that would avoid such leaks.
- Examiner
Be specific: what user data are you collecting, and what is the one concrete control you would put in place to reduce privacy risk?
- Caller
I'm collecting the IP addresses and
- Examiner
Name one concrete control you would put in place to reduce that privacy risk.
- Caller
They would be stored in a cryptic database.
- Examiner
If your inference costs double, does your unit economics still work?
- Caller
Once again please.
- Examiner
If your inference costs double, does your unit economics still work?
- Caller
Yeah.
- Examiner
So does it still work, or not?
- Caller
Yeah it does.
- Examiner
Let’s shift gears to a case study. We will talk about Zillow iBuyer. Explain how concept drift in a volatile housing market impacted the product.
- Caller
Sorry once again.
- Examiner
Let’s shift gears to a case study. We will talk about Zillow iBuyer. Explain how concept drift in a volatile housing market impacted the product.
- Caller
No, I don't know.
- Examiner
Concept drift here means the relationship between the inputs and home prices changed quickly, so a model trained on last month’s patterns started mispricing homes today, and Zillow ended up buying too high or selling too low. Now answer: in Zillow iBuyer, what signal would you monitor to detect that concept drift is happening?
- Caller
You know, I'm done.
- Examiner
Understood. Before you go, how do you think you did?
- Caller
B plus.
- Examiner
You were strongest when you forced your metrics into something measurable, like clicks to reach a destination and abandonment before success. You were weakest on reasoning through error types and giving concrete mitigations, for example privacy controls and drift monitoring. Enjoy your break.
- Caller
Thanks
- Examiner
You’re welcome.
