FE system design of the credit card application page
1. Divide an array into two subarrays whose absolute difference of sums is minimum 2. Build Tabs component in React inspired from Material UI 3. Project discussion
1. Hackerrank: 5 UI/FE related questions, two easy/average algo problems in JS (nothing like binary trees, etc. but a real-life problem), plenty of time to do this. 2. Code Review - I was tasked to conduct React/TS code review on a PR consisting of 4 files. The focus was not only on the functionality but on performance, accessibility, maintainability, and readability too. 3. Questions - UI/FE related questions inside Miro. You are presented with a wireframe and asked how would you code it (without actually coding it - you are just discussing). Other questions were focused on FE security, accessibility, etc. Be aware, that they are going to ask you more and more questions about a specific topic (going deep) until you are not able to answer - it's not bad to say "Yeah this I don't know anymore." 4. Behavioral Interview - classic behavioral questions like conflicts with colleagues, co-op styles, your failures, achievements, etc. They are going to send you a link to the STAR method before, so check that out - they expect you to answer according to this format here.
