Some sample questions asked
Cisco Systems Inc. is an American multinational corporation operating with its headquarters in San Jose, California at the United States. The company is engaged in designing and selling of communication technology, voice, networking, consumer electronics and services. In India, Cisco Systems India was established in the year 1994 with the marketing and sales presence spread across importance cities in the nation.
Recruitment by Cisco:
Cisco recruits candidates either through campus recruitment in colleges or through its own offices in different parts of the nation. Irrespective of the place of recruitment, the company recruits candidates by conducting recruitment examination in the form of written test followed by interview.
Cisco placement exam pattern
CISCO selects technical candidates through written test for a duration of one hour and the question paper for this written examination will have three sections, where in section 1 will be common for all candidates and second and third section will have questions based on the specialization branch of candidates. The first section of the question paper will have questions from the following areas:
⢠Number representations
⢠Small numerical
⢠Virtual memory
⢠Microprocessor
⢠Architecture
⢠Flip flops
⢠Digital logic design
The second section of the question paper will be devoted for questions from software related areas, while third section is meant for questions from hardware area.
Cisco Previous years question papers:
Candidates, who are going to face Cisco placement examination can practice with the help of the previous years question papers of Cisco placement exam papers
