Marcos P. - "Your approach was illuminating for sure, particularly the use of frameworks for stories."See full answer

Riku H. - "Great question. Before I start can I start asking some clarifying qs? By video I am assuming this is FB videos where it's selectively fed unto the newsfeed correct? Yes For FB events should the user be fed with their events, their friends, events or also events in their network? Good Q. I would say yes for the purpose of this question that that's all in scope. Is videos the same as reels? No in this case they are similar but different products where FB videos do not have the 90 sec t"See full answer

Frederick A. - "This problem can be solved with two approaches Iterative approach Recursive approach Quite easy to think about the iterative approach, you can make use of a while loop in that case. But what if you want to make use of previously computed values? That case going for the recursive solution is quite useful. class Collatz: def init(self) -> None: self.cache = {} self.steps = 0 def steps_from(self, n) -> int: # base case if n == 1: "See full answer

Aiden L. - "clarification define a handyman: someone who's paid to do minor renovations or domestic repairs. define the app: standalone or within facebook or meta's app family? why are we designing this? should I come up with a goal (engagement, monetization)? constraints (financials/timeline)? goal: adoption. since it's a new app, i want ppl to adopt first and then monetize the users. I'd define a handyman as someone who's paid by app users to do minor fixes, such as unc"See full answer

Scott S. - "my team is distributed across different regions, different time zones. Managing distributed teams presents unique challenges and opportunities,. I have developed a structured approach to ensure effective collaboration, communication, and productivity. I follow various strategies, as follows: I schedule regular meetings, including daily stand-ups, weekly syncs, and monthly retrospectives. This ensures that everyone stays aligned and up-to-date on team progress and priorities. I leverage commu"See full answer

Exponent - "This is a Measure Success question with a slight twist. The twist here is we need to consider a hypothetical product rather that one already built. This changes our formula slightly - specifically we may not be able to apply a UX flow to drive analysis since we're unsure of the implementation. Instead, we'll look at core behaviors that are indicative of success. Here's the modified formula: Ask clarifying questions State the goal of the feature **Apply a UX flow to drive a"See full answer

Nishtha - "How much does the Empire State Building weigh? I will estimate the weight of the Empire State Building using a structured approach. I’ll start with clarifying questions, define an equation, make reasonable assumptions, perform calculations, and address trade-offs and potential errors. Clarifying Questions To refine the scope, I considered: How many floors does the Empire State Building have? What is the area per floor? What materials are used (e.g., steel, concrete)"See full answer

Erjan G. - "this task is misleading . i used lag(1) and lead(1) cuz it did not say "compare temperature from 2 days before and 1 day before" , it reads to me as if its asking "compare cur temperature to prev and future and see if it rose and fall""See full answer

Nagi E. - "SELECT zip, SUM(rides), SUM(deliveries) FROM rides_deliveries GROUP BY zip_code;"See full answer

William M. - "Relu = 0 if > some threshold else x sigmoid normalizes to 0-1 asymptotically"See full answer

Nick S. - "[I'm not sure whether the answer below is the best, as I have not gotten result and feedback from my interview] Ans: I would solve by first using a VAE-style model, to create a latent space embedding that translates user description to generate images. Training would be done on the 1000 avatar images and 100000 descriptions, following this scheme: VAE: description -> encoder -> latent space -> decoder -> image Q: "OK, but that means you're limiting the generated images to be only the 1000 imag"See full answer

Surbhi G. - "My preference would likely be server-side deployment given the specification of millions of users. However, it is worth considering a hybrid model too; where basic, non-sensitive, and less compute intensive tasks are processed on the client-side, while the heavy-duty processing is done on the server side. The main advantage of client-side deployment is it can work in real-time and offline. It also significantly reduces the load on your servers, making it more efficient in handling other tasks.

Tanu M. - "Google Home is an app that is used by consumers to configure the smart devices for automating their home and making their home more reliable and easy to use. Clarifying questions : Do we have any time constraints by when we need to achieve this? IF we have to increase sales by 10x, it needs to focus on number of factors like increasing the partner base, improving user experience, and shift in thinking. What metrics we focus on Monetization - Making revenue 10x Number of"See full answer
