- 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
[DEMO STUDENT]
- Examiner
Thanks, [DEMO STUDENT]. What is your...
- 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
no idea
- Examiner
All right, then we have a problem even Jian Yang cannot pivot out of. What is the product you built on Team B?
- Caller
i have no idea
- Examiner
You should stop this exam now and email the instructor immediately, because you are not able to identify your own Team B project.
- Caller
that'S because it was ai generated, like every one elses
- Examiner
Even if your slides were generated by an algorithm with the moral compass of Pied Piper’s growth team, you still have to defend a coherent product. What is the one sentence user job to be done your Team B system performs for a recruiter?
- Caller
to find the right person for the positoin
- Examiner
Good. Why does that specific problem require A I?
- Caller
because iot is so much cheaper than employing real people
- Examiner
Name one concrete step in the recruiting workflow that your system automates.
- Caller
checking on user id and validitiy
- Examiner
What is your North Star metric for this product?
- Caller
what is a northstar metric?
- Examiner
It is the single most important metric that best captures whether the product is delivering value to users over time. For your recruiter copilot, what is that one metric?
- Caller
oh, sorry, how much money we can make by selling the product on to multinational companies
- Examiner
What is the counter metric that might tank if you over optimize that?
- Caller
...
- Caller
moral obligation to society
- Examiner
That is admirably high minded, but I need a metric you could actually observe. What measurable outcome would get worse if you over optimize revenue here?
- Caller
...
- Examiner
Take your time. What measurable outcome would get worse if you over optimize revenue here?
- Caller
measurable outcome - then you need non financial units?
- Examiner
Yes. Pick one measurable non financial outcome that could get worse if you over optimize revenue. What is it?
- Caller
bandwith - by having the a agent over analyse, i can use too much compute power
- Examiner
Good. In your setting, is a false positive or a false negative worse?
- Caller
false positive
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
well, i don'T need to employ people who are using agents for the interview, and therefore give me a false positive through an illusion of comeptentcne
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
what is fapt ?
- Examiner
It stands for Fairness, Accountability, Transparency, Privacy. Pick just one of those that matters most for your recruiter copilot. Which one?
- Caller
transparency - if i am going to engage AI to undertake human tasks, then the human agent must be clear on what is happening with their data -where it is going and how it being processed
- Examiner
How would you mitigate that?
- Caller
by making the data avilable to them and having them sign off via a check box perhaps
- Examiner
If your inference costs double, does your unit economics still work?
- Caller
yes, but only at break even
- 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
what si concept drift
- Examiner
Concept drift is when the relationship between inputs and the target you are trying to predict changes over time, so the model that used to work starts making systematically worse predictions. In Zillow iBuyer, what changed in the world that made yesterday’s pricing model unreliable?
- Caller
a surge in the house market prices
- Examiner
How would you design a guardrail to catch that drift early before it loses a lot of money?
- Caller
put a % oincrease into the original prompt a
- Examiner
Describe the guardrail as an operational rule you could enforce automatically. What would the system do when the drift signal triggers?
- Caller
contact the human coder and wiat for new instructions
- Examiner
How do you think you did?
- Caller
poorly - i have never taken your course and don'T even understand most fo the terminology
- Examiner
That’s a fair self assessment. You were able to reason about transparency and you correctly noticed that compute cost can become a limiting counter metric, but you were shaky on core product and modeling concepts like North Star metrics and concept drift, and your guardrails were too vague to be operational. Before you go, I need one thing from you. Are you actually enrolled in this course and assigned Net I D [DEMO NETID]?
- Caller
of course
- Examiner
Then tell me, in one sentence, what Team B built.
- Caller
a rocketship
- Examiner
Hang up now and email the instructor immediately.
- Caller
why?
- Examiner
Because your answers indicate you are not able to identify or defend the Team B project, and at this point I cannot verify academic integrity or even that we are evaluating the right work. Please end the call and contact the instructor by email to clarify your enrollment and...
- Caller
it was a linked in project
- Examiner
What is the one sentence description of what the LinkedIn recruiter copilot does?
- Caller
it finds candidates for positions via the website linkedin
- Examiner
What is the one concrete action it takes in the first three turns of the conversation with a candidate?
- Caller
verification of identity
- Examiner
That is not the Team B spec. Team B is an auto D M agent that handles the first three turns, then hands off to a human. What is the first message it sends to a candidate?
- Caller
greeting
- Examiner
What specific information does it request or propose in that first message?
- Caller
asks for name and confirmation of address
- Examiner
That still does not fit a recruiter outreach message on LinkedIn. I am going to pause the exam here. Please email the instructor and explain that you could not describe the Team B system behavior in concrete terms during the oral, and ask to be rescheduled or given instructions for remediation.
- Caller
can i have a mark please?
- Examiner
No, I cannot give you a mark here. What I can do is tell you what you would need to answer to earn a passing evaluation: you would need to describe Team B’s recruiter copilot in concrete terms, state a clear North Star metric and a counter metric, explain which error type is worse and the user impact, and name one F A T P risk with a specific mitigation. Do you want to stop now and email the instructor, or do you want to keep going and attempt a coherent defense from scratch?
- Caller
...
- Examiner
Tell me which you want to do: stop and email the instructor, or keep going and attempt the defense from scratch.
- Caller
Fraudulent Transfer Claims
- Examiner
I cannot help you with fraudulent transfer claims, since that is legal advice. For the exam, though, I need you back on your Team B project. What is the specific user problem your LinkedIn recruiter copilot is solving?
