Job Interview Questions and Answers
for a Network Administrator
Question: Do you find it difficult to work for long hours in front of a computer?
Answer: The work of a network administrator is just that – long hours in front of computers. There is not much traveling involved. Minimal physical activity may be required when troubleshooting hardware. Sometimes it is necessary to come down to the specific station to investigate the problem. But mostly, the administrator communicates via phone or internet and offers support from behind his own desk.

Question: What would you say characterizes a professional network administrator?
Answer: Network administrators are typically enthusiastic about everything computer related and have a perfect understanding of what might go wrong. They are friendly people, though not necessarily charismatic leaders or great speakers. They give quick, cordial, and, most importantly, extremely efficient service.

Question: What experience do you have with security support and maintenance?
Answer: Network administrators deal primarily with whole systems of corporate computers. They are hired to plan out in advance the company’s computer security. They implement it and perform regular maintenance. Security involves firewall installation, cryptography, adding or deleting users, backup and recovery, etc.

Question: Are you familiar with network architecture?
Answer: Network administrators deal with systems. These systems have what is called “architecture.” Some administrators, but not all, specialize in the structure of computer systems.

Question: How do you perform system maintenance?
Answer: Network administrators run checks to detect and prevent bugs, breakdowns, viruses, hackers, etc. They are always up-to-date with the latest enhancements in the market and install upgrades whenever necessary.
