I applied through a recruiter. The process took 1 week.

First the typical recruiter call then straight into a live coding. There was no job description or any sort of prep besides the super generic "you will work to solve a coding challenge based on common algorithms and data structure using Typescript". Any questions for more details and areas to prep for went unanswered. Both recruiter and the coding interviewer were polite and engaged so that is a plus. Their interviewing process is just as flawed as all the companies who judge your abilities by LeetCode exercise (even though theirs wasn't exactly one. It was just a speed coding test for a random problem). Posting the questions in hope this helps someone and shows the company that live speed coding of a random problem says nothing about the actual person's abilities and what they would contribute to the company in the real world. Hope you pass by this unreasonable gate and show them your real skills.

Given a set of mock APIs and some types, write a function that would load user + their friends + their posts (which include a list of likes from other users).
