HR contacted me via a job portal and sent an email with programming questions to solve over the weekend. I was then called for an in-house interview. During the in-house interview, I was given another question paper with a total of 8 programming questions to solve in 30 minutes. I did not clear this round.

Find Pythagorean triplets in a user input array and write test cases for it in TestNG/JUnit.

Find the shortest distance between two elements in a 2D array and write test cases for it in TestNG/JUnit.

Find the missing number from an arithmetic progression.

String Palindrome, reverse words in a string, find the longest substring in a string, and find duplicate characters in a string and print their counts.
