- 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 ...
- Caller
name: [DEMO STUDENT] netid: [DEMO NETID]
- Examiner
Great, hello [DEMO STUDENT]. I have your Net I D as [DEMO NETID], that matches. You worked on Team B. Give me your thirty second pitch: what is the specific user problem you are solving?
- Caller
that the user needs to test whether or not the students he taught were actually writing the code that they said they did
- Examiner
So you are solving instructor verification of student authored code, not just claimed work. Good. And why does that specific problem require A I?
- Caller
Because the particular problem doesn't scale, and because it doesn't scale, I have to put it in the AI, I guess, yeah.
- Examiner
Fair. Humans do not scale; that is basically the entire business model of Silicon Valley. What is your North Star metric for this product?
- Caller
Portion days of students who successfully pass the test.
- Examiner
What is the counter metric that might tank if you over optimize that?
- Caller
Students actually stop learning and start learning, stop learning to code and start learning what's the trick, how they can trick the AI examiner basically.
- Examiner
In your setting, is a false positive or a false negative worse?
- Caller
False positive is worse.
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
That's okay I would like to end the exam here just please give me whatever grade I got.
- Examiner
I can stop the questioning, but I cannot give you a grade here. Before we end, answer this one to finish cleanly: what is the concrete harm if the system falsely accuses a student of cheating when they did the work?
- Caller
Well they failed the course and that's pretty bad particularly if they're senior then you know that's horrible.
- Examiner
Understood. That is real harm: an incorrect accusation can derail graduation and trust in the institution. 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
I don't know.
- Examiner
How would you design a...
- Caller
I just don't.
- Examiner
That is fine to pass. How do you think you did?
- Caller
I think I did okay on the first part but kind of terribly on the second.
- Examiner
That is an accurate self assessment. You were solid on articulating the user problem, the need for A I, and you correctly identified that false positives are worse with concrete real world harm. You struggled on the case study, and you ended the defense early, which limited how much you could demonstrate. Enjoy your break.
- Caller
Okay.
- Examiner
All right. If you need anything administrative, email the instructor from your N Y U account.
- Caller
Okay
- Examiner
Take care.
- Caller
...
- Examiner
I’m here. What would you like to do next?
- Caller
Nothing else just end the call.
