Experience:
This Tesla Frontend Role interview experience comprised four rounds, each starting with basic information and concepts before moving to the main topic.
General Topics across rounds:
- Basic concepts of JavaScript and DOM, such as Closure and event-related topics.
- Collaborative coding in coderpad.io.
Specific Coding Questions:
- Given a color block on the left, a color block on the right, and a step count N, implement a color gradient and output the RGBA values of the two colors evenly in N steps.
- Given a string, rearrange the order of letters according to frequency of occurrence (e.g., "hello" => "llheo"), using the idea of a map.
- Determine whether the letters that make up two strings are the same (e.g., fob, bfo => true; kog, koo => false).
- Promise, async/await usage.
System Design:
- Design the front-end architecture of a three-step Tesla order page (Address book, payment, confirmation), where only one step is active and others are grayed out/disabled.
CSS Questions (3 small questions):
- Use Flexbox to horizontally and vertically center one box in another.
- Use Flexbox to arrange boxes A and B side-by-side on a large screen, and B on top, A below on a small screen.
- Without adding classes or IDs, give the three elements under an 'a' tag different colors.
