- 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] [DEMO NETID]
- Examiner
Great, hello [DEMO STUDENT]. Your Net I D matches. Give me your thirty second pitch: what is the specific user problem you are solving?
- Caller
Logging into a learning management system.
- Examiner
And why does that specific problem require A I?
- Caller
Because it's fun.
- Examiner
Fun is not a product requirement, it is what happens after you ship. What is the concrete reason this login problem requires A I?
- Caller
Users are having too much issues with it and they need a better alternative that is faster because they need to be able to access it in a much faster time period.
- Examiner
What is your North Star metric for this product?
- Caller
Decreasing the time for logins by 50%.
- Examiner
Good. Now, what is the counter metric that might tank if you over optimize that?
- Caller
Number of users accessing the system may drop.
- Examiner
In your setting, is a false positive or false negative worse?
- Caller
False positive.
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
People start using something else besides the recommended system.
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
What is an FATP issue?
- Examiner
F A T P stands for Fairness Accountability Transparency Privacy. Pick one issue relevant to your domain.
- Caller
Equitable access for everybody.
- Examiner
How would you mitigate that?
- Caller
Ensure that everybody has equal access to be able to log in.
- Examiner
If your inference costs double, does your unit economics still work?
- Caller
Not sure.
- Examiner
Give me one concrete assumption about your pricing or cost per login that would let you answer that.
- Caller
I have no costs for the login. It's a free system to use.
- Examiner
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.
