Cisco interview questions

I had 4 interviews involving a Vice President, Director, and 2 Controllers. Unfortunately, the interviews were not all at once and I had to have them across a couple of days. They each had their scripted questions supplied by Human Resources. The hardest part was having a couple of them on the phone versus in person.

we initially had a written test of multiple choice questions- Data Structures, Algorithms, Aptitude, basic Electronics concepts. A shortlist of 20 out of 150 people was announced. and the interviews commenced thereafter. I had two rounds of interviews In my first round- Code to determine a loop in a singly linked list explain and provide algorithm for quick sort basic questions on operating systems questions based on my resume The second round entirely focused on Big Data due to my experience in the field.
