TAC At Cisco Systems Interview

TAC At Cisco Systems
San Jose, CA

I applied online and the process took 4 days - interviewed at Cisco Systems in December 2012.

Interview Details – Applied for this position online and got contacted the next day by a recruiter at Cisco.
Started with a prescreen phone interview for 10 mins (nothing technical) why-do-you-want-to-work-for-Cisco type of question. and some info about myself.
Two days later had a technical phone interview, with a friendly engineer; the following week had an onsite interview via Teleconference since I am in the East Coast and the position is in San Jose, CA.
Prepare to get technical with troubleshooting questions, etc.... scenario based questions and personality questions as well, what-would-you-do-in-this-situation type of questions since this is a customer support role.
Got my offer letter the next day.

Interview Question – Scenario based question when a computer needs to talk to another computer on a different network..... word of advice, know all the fields in the layer 3 packet to answer this question.   Answer Question

Negotiation Details – Didn't negotiate, all I asked for was a compensation equivalent to the market value since this is my first job

Very Difficult Interview

TAC Customer Support Engineer Interview

TAC Customer Support Engineer
Diegem (Belgium)

The process took a day - interviewed at Cisco Systems in August 2009.

Interview Details – The phone interview was technical, with pointed questions on security protocols and in-depth networking knowledge. After passing that, I was invited for a day of interviews. There were 8 interviews in total, 6 technical, and 2 managerial. The technical ones consisted of troubleshooting on a whiteboard, analyzing network diagrams, doing netmask calculations, and explaining the analytical process out loud. The managerial interviews were just to see if you would fit in to the group. The technical interviews were quite tough, with very senior people asking you pointed question. What they were after was not always the right answer, but instead to see you troubleshoot and explain your thought process out loud.

Technical round was mostly about networks, a little bit of C coding, a little bit of OS.

Puzzle solving, analytical skills.

HR round and Managerial round, simply tested your mindset, and how you will apply your knowledge towards situational scenarios.
