- 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] Rizikos, net ID 123456789.
- Examiner
Your Net ID does not match what I have on file, which is [DEMO NETID]. Please hang up and email the instructor immediately so we can sort out the identity check before continuing.
- Caller
Okay, my ID is [DEMO NETID].
- Examiner
Great, hello [DEMO STUDENT]. I see you worked on Team what is your team letter?
- Caller
A.
- Examiner
Great. You worked on Team A, Uber Ride Guardian. Give me your thirty second pitch: what is the specific user problem you are solving?
- Caller
I'm solving the problem of understanding and grouping users of Uber's app and how they interact with the app and how they can be grouped in different segments.
- Examiner
That sounds more like customer segmentation than driver safety, so I am going to make you be painfully specific, like a Pied Piper demo that actually has to work. What is the specific safety problem Uber Ride Guardian solves for drivers or riders in the moment of a trip?
- Caller
That the riders do not veer off or change the destination.
- Examiner
And why does that specific problem require A I?
- Caller
Because I would need to understand whether the path that the driver has chosen, which does not align with the Uber app's AI proposed path is in fact an alternative path or if the driver is trying to kidnap the Uber customer instead.
- Examiner
What is your North Star metric for this product?
- Caller
number of kidnappings per year per driver.
- Examiner
Good. Now, what is the counter metric that might tank if you over optimize that?
- Caller
Number of successful trips per driver per year.
- Examiner
In your setting, is a false positive or false negative worse?
- Caller
A false negative would be definitely worse because we're talking about kidnappings here.
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
Well, if a driver has not been identified as having kidnapped a customer, which would be a false negative, and that would be definitely bad to have drivers out there that kidnap their customers that have not been identified.
- Examiner
Pick one F A T P issue relevant to your domain.
- Caller
Model optimization.
- Examiner
I do not understand. Pick one F A T P issue relevant to your domain.
- Caller
I don't have an answer. Can you provide me a clue?
- Examiner
Pick just one: fairness, accountability, transparency, or privacy. Which one is most relevant here?
- Caller
Accountability.
- Examiner
How would you mitigate that?
- Caller
By making the drivers more accountable.
- Examiner
Be concrete: who is responsible when the system flags a possible kidnapping, and what action do they take in the product?
- Caller
Can you tell me if I have a chance of passing this exam?
- Examiner
I cannot predict or promise an outcome, and I will not pre grade you mid exam. Right now you are giving me vague answers, and vagueness is the fastest route to a bad time. Who is responsible when the system flags a possible kidnapping, and what action do they take in the product?
- Caller
I feel uncomfortable continuing this conversation. I would like to end this exam.
- Examiner
Understood. We will stop here. Please email the instructor as soon as you can to explain that you ended the oral exam early due to discomfort and to ask about the next steps and rescheduling or alternative arrangements. If you are in any immediate...
- Caller
Okay.
- Examiner
All right. Please go...
- Caller
Thank you.
- Examiner
You’re welcome. Please email the instructor now, and if you decide you want to continue later, do it through the official process.
- Caller
Okay. Thanks.
- Examiner
You’re welcome. Take care, and follow up with the instructor for next steps.
