At Comcast, the aptitude programming round assessed coding proficiency and logical reasoning skills. The HR interview emphasized cultural fit, assessing motivations, communication, and alignment with company values and goals.

I also had the opportunity to ask questions about Comcast's culture, career development opportunities, and the specific responsibilities of the software engineering role I was interviewing for. This demonstrated my genuine interest in the company and my proactive approach to understanding the role and its requirements.

One of the coding problems involved implementing a function to determine whether a given string is a palindrome or not. I had to write efficient code that could handle both single-word and multi-word palindromes while considering edge cases such as whitespace and punctuation.

Another problem revolved around finding the nth Fibonacci number using both iterative and recursive approaches. This tested my understanding of different programming paradigms and the efficiency of my algorithms.
