Juniper Networks interview questions

First round: Written test: 15 IQ/Aptitude/Intelligence questions 35 Technical questions from Networking,OS,Data Structures,C,C++,,S/w Engg etc Second round and Third round : Technical face-to-face Questions based on Resume+other technical Fourth round: HR

I had 2 telephonic screes. All the questions were on C,data structures and networking. Finally they called up for on site interview. First day it was 4 rounds with each of them stressing on data structures/algorithms. Some details on projects and networking is also stressed upon. After one week they called for next level of interviews which is again 4 more rounds. This time hiring manager,Group manager and Head of the BU involved interviewing. In my opinion its really a tedious and long process. I dont see any reason for 2 phone + 8 rounds of 1:1 interviews. Finally they told they would make an offer.
