• "Tell me about yourself, and why you want to join CDOT."
• DSA Question: "3L jug and 5L jug unlimited water problem." The candidate provided two solutions.
• DSA Question: "Second largest element in an array." The candidate explained both naive and optimized approaches and then coded it.
• "Difference between array and linked list."
• "What is storage class? And types and differences between them?"
• C Programming Question: Given an array a[]= {12,43,56,8,3,545,89};, "traverse through a pointer to the whole array and when you come across the 3rd index, change the value from 56 to 30."

The candidate mentioned being nervous and not performing well on the pointer questions, having prepared primarily for AI-ML topics.
