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 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

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

Exponent - "This is a Strategy Question, which asks you to justify high-level business decisions and strategy. There's no set formula, but we recommend proposing at least three different reasons to answer the question. Let's go over one possible solution: > I think there's three major ways Uber was impacted:Hiring uncertainty > A focus on Eats > Assisting local restaurants > Hiring uncertainty > I think one of the major ways Uber, and any tech business, was affected is in hiring new talent.
