Interview Questions

Scott S. - " Situation Our data engineering team was tasked with developing a new real-time analytics platform for derivatives trading. To ensure the project’s success, we needed buy-in and support from various non-technical teams, including finance, compliance, and senior management. These teams needed to understand the importance of the project, the resources required, and how it would benefit the organization. Task My task was to effectively communicate the technical requirements and benefits of"See full answer

Surbhi G. - "While serverless computing has its merits due to removing the need for server management and auto-scaling abilities, several challenges might arise when deploying machine learning models using this setup. Cold-start latency is a key issue where an Amazon Lambda function, for example, would take more time than usual to run after being idle. This could affect the performance of real-time ML applications negatively. A way to keep the functions warm might be required to avoid this latency. Moreover,"See full answer

Constantin P. - "Reinforcement Learning is a type of machine learning where an agent learns to make decisions by trying out different actions and receiving rewards or penalties in return. The goal is to learn, over time, which actions yield the highest rewards. There are three core components in RL: The agent — the learner or decision-maker (e.g., an algorithm or robot), The environment — everything the agent interacts with, Actions and rewards — the agent takes actions, and the environmen"See full answer

Taha U. - "In details: setting k=1 in KNN makes the model fit very closely to the training data, capturing a lot of the data's noise and leading to a model that may not generalize well to unseen data. This results in a high-variance scenario."See full answer

Vivek S. - "Hey team, the title says a "GTM campaign" whereas the video is about "favorite marketing campaign" example. Are they supposed to be the same? If not, can you please fix it?"See full answer

Exponent - "This is a Favorite Product question with a slight twist. We have a constraint: picking a physical product. This should be relatively easy since you use physical products personally every day. Let's go over the Favorite Product formula before we begin: Choose a product and briefly explain what it is Who are the users? What are their pain points? How did competitors solve it in the past? How does this product address these pain points differently and better? "See full answer

Shashi R. - "How do you define Retention? Let’s assume a user comes back tomorrow and scroll for a 10s or so Do we mean to improve the daily retention or weekly/monthly retention? Take a call I think we should look at the weekly retention as checking LinkedIn daily could be a cumbersome task for some and daily retention data may have frequent fluctuations due to several reasons such as professionals are too busy to check LinkedIn on a daily basis Has retention dropped recently, or do we just need to"See full answer

Will P. - "The first step is to clarify what the interviewer means by a sales decline. Questions I would ask here include: Did sales drop suddenly or gradually? What is the magnitude of the sales drop? Are sales down for a specific product? Are sales down for a specific channel (drive-thru, walk-in, etc.)? This series of questions is to make sure we are on the same page when we say 'sales are down.' We may not know the why yet, but the what should be easy to align on. Otherwise, how would"See full answer

Nidhi S. - "I am a book reader, so I use "goodreads" by amazon to track my reading. There are couple of things which can be done to increase user engagement on app. User engagement on goodread is creating profile tagging books - want to read, reading, completed marking up progress on daily reading. Engaging with friends and their feedback about books. Solutioning at each steps Creating profile - App respond time is 2-3 min, which is very slow as compared to any general app,its circling"See full answer
