The interviewer didn't ask about my experience or what I’ve done at my current company, which suggests they hadn’t read my resume. With over 10 years of experience, I expected they would have had some questions if they had reviewed it. Instead, they jumped straight into Linux questions. While I was able to answer about 50% of them, it's important to note that as a network engineer, Linux is only a part of my job, not the entirety. When the interviewer moved on to networking, I was able to answer all of those questions confidently. However, it seemed like they were overly focused on Linux, perhaps under the impression that proficiency in Linux is synonymous with a deep understanding of networking concepts like routing protocols, VPNs, STP, VLANs, WLAN, etc. This experience made me feel like they’re operating under a misconception that knowing Linux alone can solve complex networking problems.
