4 rounds: 1st: Hiring manager discussion, he asked more about my daily roles and responsibilities based on which he probably decided whether to proceed with me or not. Also a basic question to implement a Queue class using Typescript (enque and deque methods). 2nd: Take home challenge, it was on trees. Build the tree on UI with whatever user types (ex. 2+5+7) , then deletion of a node of the tree, and the UI to be synced accordingly. Then a 60min code walkthrough session with 2 engineers, who check about the approach used to solve the problem, the best practices used etc. 3rd: System design round.Standard High level system design that gets asked in any big tech, and then going deep into Low level design of a specific component. It was of 60mins. 4th : Culture fit (just for namesake :P)

The process took place very fast, in my case just in 3-4 weeks it led to offer. As I remember just the day after I submitted my CV I received a mail for the first HR call, then after that I got an assessment task to do in less than 1 week after that a technical interview with two of the lead developers and it was all about the assessment project and reviewing my CV, and at the end interview with CTO.
