Referred on October 15th. Received an email from HR on October 29th and scheduled a phone interview for November 20th.

Phone Interview:

• Started by asking about projects on my resume.
• Discussed two projects: one from my previous internship using C++, and another from school.
• Proceeded to coding problems on HackerRank. There were three coding problems in total:
  • Merge sorted array
  • Check if two trees are the same
  • Validate if a tree is a binary search tree
• Received a code snippet at the end and was asked to think of test cases and fix a bug, which mainly involved completing the task to reverse an integer.
• Was given time to ask questions about the company.

That would be to fix the overflow issue in the last question.
