I was ghosted after the first round. The recruiter sent me a link to a HackerRank test for initial screening. There were a couple of questions that were of medium difficulty with a time limit of around 60 minutes. After successfully completing the tests, I never heard back from the recruiter.

Given two arrays of strings:

• One containing prefixes (area codes)
• One with a long string of numbers (phone numbers)

Return the longest prefix that corresponds to all phone numbers.

Input is a string of characters representing a text message. You need to segment this message into chunks, each of length 160 characters. Add a suffix "(1/5)" (representing pagination) at the end of each segmented message. The length of "(1/5)" is included in the 160-character limit.
