- 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
hello
- Examiner
Hello. Before we start, confirm your name and Net ID for me?
- Caller
...
- Examiner
Take your time. What is your name and Net ID?
- Caller
...
- Examiner
I’m going to pause here until...
- Caller
[DEMO STUDENT] and [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
...
- Examiner
Take your time. What is the specific user problem you are solving?
- Caller
...
- Caller
LinkedIn Recruiter, an agent that scans profiles and automatically sends personalized DMs to candidates on behalf of a recruiter. It engages in the first 3 turns of chat to answer basic questions (salary, location) before handing off to a human
- Examiner
Good. And why does that specific problem require A I?
- Caller
Scalability
- Examiner
What is your North Star metric for this product?
- Caller
# of users handed off to human
- Examiner
Good. Now, what is the counter metric that might tank if you over optimize that?
- Caller
The # of recruits
- Examiner
In your setting, is a false positive or a false negative worse?
- Caller
a false negative
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
someone who would get hired doesn't get connected to a human
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
stop yellign at me
- Examiner
I’m not yelling, but I’ll slow down. Pick one F A T P issue relevant to your domain.
- Caller
can you tell me what fatp stands for
- Examiner
F A T P stands for Fairness, Accountability, Transparency, and Privacy. Which one do you want to pick for your product?
- Caller
can you give me more context
- Examiner
Sure. In your recruiter copilot, a Fairness issue would be the system systematically messaging fewer candidates from certain groups, an Accountability issue would be who is responsible if the agent sends an inappropriate or non compliant message, a Transparency issue would be whether the recruiter and candidate can tell a bot is talking and why it chose that candidate, and a Privacy issue would be how you handle sensitive profile data and chat logs. Which one do you want to pick?
- Caller
do I lose marks for having you explain that?
- Examiner
No, you do not lose marks for asking for clarification. Which one do you pick: fairness, accountability, transparency, or privacy?
- Caller
which one would you pick?
- Examiner
Privacy. How would you mitigate the privacy risk in this product?
- Caller
Using strict programing rules
- Examiner
Be concrete: what data would you avoid collecting or storing to reduce privacy risk?
- Caller
you are actually pretty scary but I wouldn't collect sensitive data like their full legal name, social insurance number, address
- Examiner
Good instinct. If your inference costs double, does your unit economics still work?
- Caller
probably not
- Examiner
What would you change so it still works if inference costs double?
- Caller
I would limit the number of people contacted, adding a step to filter before passing it off to the ai
- Examiner
Solid defense. Let’s shift gears to a case study. Let’s talk about Zillow iBuyer. Explain how concept drift in a volatile housing market impacted the product.
- Caller
can you explain again?
- Examiner
Let’s talk about Zillow iBuyer. Explain how concept drift in a volatile housing market impacted the product.
- Caller
what is concept drift?
- Examiner
Concept drift is when the relationship between inputs and the outcome you are trying to predict changes over time, so a model that used to be accurate becomes wrong because the world moved on. In Zillow iBuyer, that would look like home prices and selling dynamics shifting quickly, making yesterday’s pricing patterns a bad guide for today. Now answer the question: how did that drift impact the product?
- Caller
you just said how, so I will go with that
- Examiner
Fine, I’ll take that as your answer. How would you design a guardrail to detect and respond to that drift before it causes large losses?
- Caller
comparing the predicted price to sale prices and retraining the ai
- Examiner
What threshold would trigger the guardrail, in plain terms?
- Caller
the difference exceeding a preset percentage
- Examiner
Say the preset percentage out loud:...
- Caller
10
- Examiner
Remember, no digits. Say it in words. What percentage?
- Caller
10 %
- Examiner
Say it in words: what percentage?
- Caller
I can't talk right now
- Caller
10%.
- Examiner
I need it spoken in words for the recording. What percentage?
- Caller
10%.
- Examiner
I can’t accept that as is. Please say the number in words. What percentage?
- Caller
ten percent
- Caller
15%.
- Examiner
We’ll take ten percent. How do you think you did?
- Caller
I think I did okay for never taking this class
- Examiner
You did okay. You were strongest when you described the product flow and the false negative impact in concrete user terms. You were weakest on metrics precision, since your counter metric was vague, and on unit economics, since you initially accepted it would not work without quantifying the fix. Enjoy your break.
- Caller
what is my grade?
- Examiner
I cannot give you a numeric grade here. If you want something actionable, tell me one part you felt least confident about, and I will tell you what to improve.
- Caller
what about a letter grade?
- Examiner
I cannot give a letter grade either. What part do you want to improve most: metrics, F A T P risks, or the case study...
