The whole process is lengthy, but the same time interesting. The first round was a light phone screening with a recruiter (30-40 minutes). Just a general questions + some basic technical (what is TCP, UDP, DNS, DHCP). The second round was on site with one of the network support engineers. Purely technical and more in-depth (again proper Layer 1, 2 and 3 questions). Nothing tricky really, but you must know very well these layers. The third round was with the technical support manager. Again similar questions + logical thinking check. e.g l was presented with the flan, without any details topology where all traffic was routed over the low-speed link. As there were no details of the link speed etc, you should ask, confirm and make next action plan on how to resolve the issue. Start troubleshooting from Layer 1 (check CRC errors) and so on. The fourth round was on site again with three different tech manages. Checking personality, how you would react in the certain situation and again tech stuff. Tech stuff is fine as long as you know Layer 1, 2 and 3 very well.

Entrevista cordial y profesional. Preguntas claras sobre experiencia, habilidades técnicas y trabajo en equipo. Buen ambiente, entrevistador atento. Dejaron espacio para dudas. Me sentí cómodo y valorado como candidato. Todo muy bien
