We also implemented new measures to prevent a similar issue from occurring in the future.

  Answer: Communication and collaboration are crucial in any job, and I ensure to communicate in a way that my non-technical colleagues can understand. To do this, I try to use simple and clear language, avoid technical jargon, and provide visual aids when necessary.

Technical Skills & Experience

• 6. What programming languages are you proficient in?

• 7. Can you explain the difference between TCP and UDP protocols?
  Answer: TCP (Transmission Control Protocol) is a connection-oriented protocol that ensures reliable and ordered delivery of data packets between devices. UDP (User Datagram Protocol), on the other hand, is a connectionless protocol that provides faster delivery of data packets but does not guarantee reliability or sequencing. TCP is often used for applications that require highly accurate data transmission, while UDP is used for applications that can tolerate occasional data loss, such as video and audio streaming.
• 8. What is the difference between a router and a switch?
  Answer: A router is a networking device that connects two or more networks and forwards data between them, using routing protocols to determine the best path for data transmission. A switch, on the other hand, is a networking device that connects devices within a network, using MAC addresses to direct data to the appropriate device on the network. In simple terms, a router connects networks, while a switch connects devices within a network.
• 9. How do you handle network security threats?
  Answer: A proactive approach is crucial in handling network security threats. I regularly perform vulnerability scans and penetration tests to identify any weaknesses in our network and systems. I also keep systems and software updated with the latest security patches and regularly monitor network traffic for any suspicious activity. In case of an attack, I have experience in isolating and containing the threat while working towards a solution with the help of my team.
• 10. How do you ensure data backup and recovery?
  Answer: Data backup and recovery is a critical aspect of IT, and I have experience in setting up and managing backup systems to ensure that our data is always protected and easily recoverable in case of hardware or software failures. These systems include regularly scheduled backups, off-site storage, and periodic tests of the backup and recovery processes.

Situational Questions

• 11. If a coworker came to you with a problem with their computer, how would you handle it?
  Answer: I would first ask the coworker to explain the problem and gather as much information as possible to understand the issue.

I would also follow up with the coworker to ensure that the issue is resolved and provide any necessary training or tips to prevent similar issues in the future.
• 12. If a server suddenly went down during a critical time, what steps would you take to resolve the issue?
  Answer: Firstly, I would assess the severity of the issue and how it is affecting business operations. Then, with the help of my team, I would try to identify the cause of the server failure and work towards restoring it as quickly as possible. If necessary, we would implement a backup or temporary solution to minimize disruption to business operations. I would also communicate with stakeholders to keep them updated and manage expectations.
