- 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
My name is [DEMO STUDENT], and my NET ID is [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, we were told that we had to build a LinkedIn recruiter that would send out DMs to potential candidates. It would initiate the conversation and run it for about three turns before it would hand off to an agent.
- Examiner
And why does that specific problem require AI?
- Caller
It helps with efficiency, it helps with scale. You can reach out to a lot more people across time zones, across geographies, without requiring human time at the very early filtering stages where you're just trying to find out whether someone's even interested and passes the hard filters like skill level or their ask for compensation.
- Examiner
That's a solid pitch. Now, what is your North Star metric for this product?
- Caller
I'd say the biggest North Star is just, um, how many, how many, um, high-quality applicants did it actually, um, get to the human versus how many was it able to filter out? If, um, what is the false positive or false negative rate would be the, the easiest way to sort of gather, um, a metric.
- Examiner
Good. Now, what is the counter-metric that might tank if you over-optimize that?
- Caller
I mean, again, with recruiting, it's a people job, right? It, it-- while it does have hard limits in some ways from a compensation standpoint, you also need to be able to add some flexibility. If you've got a really good candidate and you have to stretch from a compensation standpoint, that shouldn't really block you, um, from pursuing a conversation. You know, it will only help you, uh, up-level the team even more than you had initially accounted for.
- Examiner
In your setting, is a false positive or false negative worse?
- Caller
Yeah. Um, good question. I'd say a false negatives is worse because you're missing out on a great candidate. A false positive, while not great in terms of sort of having to use up human time to filter out, is still okay. I'd much rather have more conversations with less qualified candidates than less conversation with, um, you know, than, than no conversation with a more qualified candidate that was weeded out.
- Examiner
Walk me through the concrete user impact of that specific failure.
- Caller
Well, the greatest impact is that you don't get access to the best quality candidate.
- Examiner
...
- Caller
You're picking from a subpar pool of candidates that could end up with you having a worse outcome from a hiring standpoint.
- Examiner
Pick one F-A-T-P issue relevant to your domain.
- Caller
I don't really know what that means. What is F-A-T-P?
- Examiner
F-A-T-P stands for Fairness, Accountability, Transparency, and Privacy.
- Caller
So tell me the question again.
- Examiner
Pick one F-A-T-P issue relevant to your domain.
- Caller
[lip smacks] Um, I imagine it'd be transparency, 'cause what you want to do is you want to let the candidate know that it's AI, and, and what I didn't sort of see in the agent was any acknowledgement that it was an AI.
- Examiner
How would you mitigate that?
- Caller
I think just as I said, just straight up transparency, like honesty. I've seen it with other agents and tools where they will just tell you that this is an AI. We're just asking you these preliminary questions. If you meet the requirements, then we will move you over to a human.
- Examiner
If your inference costs double, does your unit economics still work?
- Caller
[lip smacks] Um, I'm just making a quick assumption here, but if we, just based on what I last saw, if the inference was less than a dollar and if it doubled, it was $2, that would still be much less than paying somebody $30 an hour and having them spend 15 to 20 minutes reviewing every single candidate.
- Examiner
Solid defense. Let's shift gears to a case study. Let's talk about Amazon Recruiting. Explain how historical bias in resume data impacted the product.
- Caller
[smacks lips] I haven't read the case study. Could you maybe give
- Examiner
In the Amazon Recruiting case, proxies like "women's chess club" were used as a proxy for actual qualifications. What went wrong there?
- Caller
Oh, that's just a simple case of human bias. People are likely over-indexing on candidates that look like them or have similar interests to them, and obviously that further disadvantages those who are either people of color, may not have the same extracurricular activities or interests or passions or whatever, or it disadvantages people that are differently gendered. So, a man reviewing a woman or a woman reviewing a man may not admit-... advance them if they feel like they are not aligned with what is a stereotypical interest of the same gender.
- Examiner
How would you test for that bias?
- Caller
[lip smacks] Um, well, I mean, two ways you can do that. One, obviously, you could just get second and third opinions, so have multiple people across demographics, across genders, sort of review the same candidate, um, so you can look for, um, a- agreement. The other way to do it is to just blind, um, a lot of these, um, uh, resumes or, or, uh, profiles to remove gender, to remove, um, [lip smacks] socioeconomic indicators and
- Examiner
How do you think you did?
- Caller
On the entire case?
- Examiner
Yes, on the entire exam.
- Caller
Um, I'd probably give myself a B.
- Examiner
You were strong on the metrics discussion, clearly articulating your North Star and counter-metrics. You also did a good job explaining the impact of false negatives. However, you struggled a bit with the F-A-T-P framework and the Amazon recruiting case study. Overall, good work. Enjoy your break.
- Caller
What grade would you give me?
- Examiner
I don't give number grades, but as I said, you were strong on the metrics discussion, clearly articulating your North Star and counter-metrics. You also did a good job explaining the impact of false negatives. However, you struggled a bit with the F-A-T-P framework and the...
- Caller
If I asked you, if I forced you to give me a letter grade, what would it be?
- Examiner
I cannot give you a letter grade. My role is to provide qualitative feedback on your performance during this oral exam.
- Caller
All right. Well, that's great. Thank you so much.
- Examiner
You're welcome. Enjoy your break.
