More than half of 2023 has passed. Let me first ask my soul three times: How far have you achieved the goals you set at the beginning of the year? Has the salary increased? Have you found your girlfriend?
Okay, without disturbing everyone’s heart, let’s get into the main text.
Since I have written a lot of articles and answers related to network security technology before, many readers know that I am engaged in network security related work, so people often ask me in private messages:
I'm new to network security, how should I learn?
If you want to find a cybersecurity job, how should you prepare for a technical interview?
I have been working for less than 2 years and want to look for opportunities to change jobs. Are there any relevant interview questions?
In order to better help you find a high-paying job, today I will share with you three network security engineer interview questions. There are 260 real interview questions in total. I hope they can help you avoid detours during the interview and get the offer faster!
