Ashish B. - "Ada Lovelace. There is much to admire about her: her strict analytical thinking coupled with the spirit of creative vision, which recognized a possibility for computers to do more than simply calculate at a time when it was considered revolutionary. Her ability to bridge between disciplines and see the connections between maths and science and even to poetry resonates within me. I also appreciate how she pursued intellectual passions in the face of huge gender barriers in her time."See full answer

Exponent - "This is a 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 equat"See full answer

T I. - "Idempotence refers to the property that the same request multiple times produces the same result on the server side. No matter how many times I repeat the request, the server state does not change after the first request. This concept is important to ensure consistency, especially in systems where requests may be repeated due to network failures or other problems. Let's take a look at different HTTP methods for a clearer understanding. GET: By definition, GET requests must be powerless. Execut"See full answer

Chao peter Y. - "The question is incomplete --- the code only passes if you return the data frame sorted by BOTH department name AND rank. While in the problem description, it mentions to only rank by department name: "The results should be ordered by department name." Not a big difference I know, but students shouldn't need to look into the solution to get the necessary knowledge to answer the question."See full answer

Sushil K. - "1. Assessment of Current Applications Architecture Review: Examine the underlying architecture of both applications. The 10-year-old application might be based on outdated technology, which could pose challenges in terms of scalability, performance, and maintainability. The 3-year-old application, on the other hand, might use more modern technologies, making it more adaptable to future needs. Codebase Quality: Assess the quality, structure, and documentation of the codebase."See full answer
