1 Know Basics

Before stepping into the interview room, ensure you have a solid grasp of the basics of computer networking. This includes understanding the OSI (Open Systems Interconnection) model, TCP/IP (Transmission Control Protocol/Internet Protocol) suite, common networking devices like routers and switches, and network topologies. You should be able to explain how data moves through networks, the role of each OSI layer, and the purpose of different networking hardware. This foundational knowledge is often tested in interviews to gauge your technical competence.

Ir preparado para, por lo menos, responder conceptos muy básicos de la currícula de CCNA actualizada; charlar con otros colegas que quizás ya hayan ido a esta u otras entrevistas; visualizar y armar un mapa mental sobre cómo será la entrevista; contar experiencias prácticas y puntuales sobre experiencias pasadas. No es el momento de mostrar enojos ni frustraciones, es innecesario. Es fundamental estar tranquilo y de muy buen humor.

2 Review Protocols

A strong understanding of key networking protocols is essential. Be prepared to discuss protocols such as HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), SMTP (Simple Mail Transfer Protocol), and DNS (Domain Name System). Explain their functions, how they operate within the network, and their significance in maintaining network communication. Interviewers may ask you to compare and contrast these protocols or to troubleshoot a hypothetical problem involving them.

Prepara tu entrevista como un juego de ajedrez, donde, como en el ajedrez, habrá una apertura, un medio juego y un final. Puedes usar un mapa mental y demás material para ayudarte.

3 Practice Scenarios

Anticipate scenario-based questions that assess your problem-solving skills. Practice troubleshooting common networking issues, such as IP (Internet Protocol) conflicts, network congestion, or security breaches. Be ready to articulate your thought process and the steps you would take to resolve these issues. Demonstrating your ability to think critically and apply your knowledge in practical situations is crucial.

4 Understand Security

Security is a paramount concern in networking. Familiarize yourself with fundamental security concepts like firewalls, VPNs (Virtual Private Networks), encryption, and access control lists (ACLs). You should be able to discuss how to secure a network and protect data from unauthorized access or cyber threats. Interviewers may present security scenarios to test your awareness and ability to implement effective security measures.
