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.

On the phone I was asked about Javascript closure, hoisting, and some problem solving/ algo question. In person I was asked to describe the output of given code, where there were timeouts and promises, how to implement debounce, and an algorithm question - finding LCA of two nodes - the nodes had reference to parent.
