3. REACT LIVE CODING (1 hour, Zoom and Codepad). Basic react problem. I needed to parse some data and display it in an existing app. It was important to be intimately familiar with react, to know my way around react hooks and think about efficiency and the readability of my code. I'd advise being particularly diligent concerning performance optimizations. Again, I was allowed to consult MDN, react docs, etc. TS or JS is fine. At one point, my computer started lagging and I had to quit the call and restart my computer. The interviewer was completely understanding and gave me some extra time.

The quiz encompassed a comprehensive range of engineering topics, spanning from frontend and backend to databases and Linux. It appears designed as a preliminary assessment to sift through candidates. The 'cultural fit' segment is an insightful two-way process. It not only familiarizes the candidate with the company's ethos and workflows but also provides the company an opportunity to understand the candidate's aspirations, career trajectory, personal interests, and more. The final segment is bifurcated. Firstly, it involves requirements elicitation and the design methodology for various features. The subsequent part requires live-coding of several client-side interfaces. During this, the candidate is expected to articulate their thought process to a lead developer. This approach provides a holistic perspective of the candidate's technical acumen and problem-solving prowess.
