Met them at a career fair and was asked to complete an online coding challenge. After the challenge I got a call to set up a phone interview. They asked a few technical questions and then a coding problem. Not too difficult but wasn't offered a job because of lack of experience. They're looking for good coders in general, but really prefer people who have experience or a demonstrated interest in networks.

Applied through university. 2 in person interviews , 1 phone call interview. Interviews asked LeetCode Easy/Medium questions (Give frequency table of every first word in a log file). Very courteous and professional!
