I saw this position on LinkedIn and applied on juniper's job portal website. Got an email from them asking me for suitable date for an on-site interview. They mentioned in the email that there would be one "Programming Test" and then "Personal Interview". On the big day the test was on C, Data Structures and algorithms. There were 21 questions and 45minutes was given. Time was not at all sufficient. Questions were also not so easy. some were easy like fibonacci series and swapping of numbers using addresses. In the personal interview, he just asked if i had any questions and told me about juniper culture and my job role.
