- 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
[DEMO STUDENT]
- Examiner
Thanks, [DEMO STUDENT]. What is your NetID?
- 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
Well, I don't really know. I just copied.
- Examiner
All right. In one sentence, what user is this for and what job are they trying to get done?
- Caller
It is for user John they are trying to cheat on exams.
- Examiner
Why does that specific problem require A I?
- Caller
In order to scale
- Examiner
What is your North Star metric for this product?
- Caller
...
- Caller
. Well,
- Examiner
What is your North Star metric for this product?
- Caller
the number of questions correctly answered by the student in the oral exam.
- Examiner
Good. Now, what is the counter metric that might tank if you over optimize that?
- Caller
The correctness of their replies.
- Examiner
In your setting, is a false positive or a false negative worse?
- Caller
A false positive is worse
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
I could blame someone for cheating when they did not.
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
Travel.
- Examiner
I do not understand what you mean by travel. Pick one of these categories: fairness, accountability, transparency, or privacy. Which one do you pick?
- Caller
Transparency.
- Examiner
How would you mitigate that?
- Caller
I would try to explain my decisions
- Examiner
If your inference costs double, does your unit economics still work?
- Caller
. It still does, yeah.
- Examiner
Give me a concrete assumption about revenue per user and inference cost per user that makes that true.
- Caller
Ten dollars versus one and a half.
- Examiner
Solid defense. Let's shift gears to a case study. Let’s talk about Zillow iBuyer. Explain how concept drift impacted the product.
- Caller
I don't feel very well, can we pause the exam?
- Examiner
Yes. Please take a moment and tell me when you are ready to continue.
- Caller
Okay I'm ready now.
- Examiner
Explain how concept drift impacted the product.
- Caller
Actually during my limited testing it did not.
- Examiner
What specific real world change would you expect to cause concept drift in home prices?
- Caller
...
- Caller
Inflation.
- Examiner
How would you design a guardrail to detect that drift early enough to stop buying the wrong homes?
- Caller
I would normalize over inflation metrics.
- Examiner
How do you think you did?
- Caller
Average.
- Examiner
That’s fair. You were clear and concrete on the false positive harm, and you could state a simple unit economics assumption. You were shaky on defining the real user problem and your counter metric did not quite match the North Star, and your drift guardrail was directionally right but too vague operationally. Enjoy your break.
- Caller
Thank you.
- Examiner
You’re welcome. If you want, tell me one thing you’d tighten first if you had one more day on the project.
- Caller
I would improve my report.
- Examiner
What specific section of the report would you improve first?
- Caller
The analysis of the results.
- Examiner
Good choice. What single plot or table would you add to make the results analysis more convincing?
- Caller
...
- Caller
The correlations table.
- Examiner
Correlations with what outcome variable, exactly?
- Caller
Let's stop!
- Examiner
Okay, we’ll stop here. If you need anything administrative, email the course staff.
- Caller
Thank you, bye-bye!
- Examiner
Goodbye.
- Caller
...
- Examiner
I’m here. If you’d like, tell me what you want to do next.
- Caller
I can't close.
- Examiner
If you mean you cannot end the call in your app, try tapping the hang up button again. If you do not see it, switch back to the app screen you started the call from and look for an end call control, or close the app completely and reopen it. Tell...
