I applied online. Four interview rounds, each split evenly between leadership principles and technical questions. Covered LeetCode problems, basic high-level and low-level design, mostly binary tree questions, plus some design patterns such as Facto

Initial phone call with a recruiter, followed by a 90-minute coding assignment. This consisted of standard LeetCode-style algorithm and data structures problems, loosely related to the specific role and easy to prepare for by using normal resources.

1 loop interview (3 rounds back-to-back) and 1 additional interview. Two LeetCode mediums: * A variation of the right side view of a BST * A variation of K most frequent elements One system design interview (Elevator system) and a lot of LP.
