Anzhe M. - "Not my answer, but rather the details of this question. It should include the following functions: int insertNewCustomer(double revenue) -> returns a customer ID (assume auto-incremented & 0-based) int insertNewCustomer(double revenue, int referrerID) -> returns a customer ID (assume auto-incremented & 0-based) Set getLowestKCustomersByMinTotalRevenue(int k, double minTotalRevenue) -> returns customer IDs Note: The total revenue consists of the revenue that this customer bring"See full answer

Priyanka S. - "I'd like to first clarify to understand where we currently stand- Have we already built the MLP pf the product or are we looking to solve for should we build this and if so, can we do this in 6 months? Assuming Scenario where the product is ready, looking for GTM feasibility I'll work with the dev and analytics team to understand the effort and timeline around experimentation. I'll also include marketing team to understand timelines post experiment if we were to launch. This will help us ident"See full answer

Daniel M. - "Clarifying questions / Assumptions: Scope: US market Constraints: none Limiting to UberX, Uberpool, UberXL services On-the-ground operations: event operations, things going on as people arrive or leave the event Defining 'events': scoping it down to concerts or large-scale events (that typically have a lot of traffic) Defining 'better experience': easier to get to and leave events Goal: I will optimize for greater user satisfaction with our service, which should translate in"See full answer

Amin S. - "We can implement Mall psychology, use the monkey effect, FOMO, top-rated stuff from the same restaurants, bundle offers like couple or group offers, and prompt popups for free delivery if you complete X$ amount by adding X item. We can lure customers by giving free subscriptions to Spotify, Netflix, etc. by collaborating with these giants. This is a long-story-short overview of how we can increase the average basket size. Tracking telemetry and refining can make a difference obviously..."See full answer

If people are preferring hourly rental over daily or weekly rental then what are the revenue implications or vice versa) Customer feedback on the rented vehicles Analysis on ge"See full answer

Exponent - "This is a Measure Success question with a slight twist. The twist here is we need to consider a hypothetical changes 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

Luke P. - "A full stack developer could be summarized as the person who both writes the APIs and consumes the APIs. They are familiar with Databases/Data-layer services, middle-layer/application services and business logic, and finally familiar with the consumers whether front-end applications/UIs or other systems. They can understand the trade-offs up and down the stack, where to adjust along the service-call-path. Ideally they are comfortable programming both async calls (front end javascript promises, e"See full answer

Exponent - "This is another Fermi problem — an estimation or approximation problem with limited information and back-of-the-envelope calculations. There's no right answer: interviewers want to understand how you think and how well you can explain your reasoning, rather than what you already know. Recall the formula for Fermi problems: Ask clarifying questions Catalog what you know Make equation(s) Think about edge cases to add to equation **Breakdown components of your"See full answer

Exponent - "Although it's not totally obvious, this is a Strategy Question, which asks you to justify business decisions at a high level. First, let's provide a few reasons why Display Ads are bad, and then propose an alternative solution. > There are a few reasons why display ads are a bad idea. I'll go into them in-depth shortly, but in summary, display ads degrade the user experience and monetize poorly, which has all sorts of cascading effects. Loss of control > Typically, display ads are run thr"See full answer
