I started by emailing my school's recruiter before the semester began. I was immediately booked for an on-campus interview on the second week of classes. This involved a standard whiteboard question and inquiries about my resume.

Following that, I was notified a week later that I had advanced to an onsite round. I scheduled this as far out as I could to give myself time to study.

During the onsite, I had five interviews in total. It was tough, but with some LeetCode practice and knowledge of Data Structures & Algorithms plus your chosen language, you should be fine.

Construct a binary tree using the preorder traversal string and the inorder traversal string.
