Cisco

They first sent me two code challenges, which were very time-consuming. One was about designing a hash on a cache layer, and the other was about Unix. I felt that it was really unnecessary to proceed in that way.

Had a phone call with HR, followed by a pair programming assignment with another person. This was primarily in Java. I then organized another interview afterwards. Unfortunately, I did not receive an offer, and the process concluded at that point.

The interview was mostly technical, featuring networking questions, followed by basic bit manipulation and linked list questions. For linked lists, a task included inverting a linked list to process it from back to front, creating an inverted list.
