A recruiter reached out about a monthly hiring event.

I completed the typical online assessment first and was then invited to a single day of four back-to-back technical interviews. Each interview consisted of 5-10 minutes of introductory chat, behavioral questions, and resume-based questions, followed by 30-40 minutes for a single technical question.

They were all LeetCode Easy/Medium difficulty. The problems were:

• Longest palindromic substring
• Smallest item in a rotated array
• Largest island in a 2D array
• Determine if a linked list is a palindrome

1. Longest palindromic substring

2. Smallest item in a rotated array

3. Largest island in a 2D array

4. Determine if a linked list is a palindrome
