I had three technical interview rounds with no good technical questions. Get ready to be asked the basic textbook TCP questions by their inexperienced technical team. They will never ask you what troubleshooting challenges you had at your current and past jobs because they themselves seem less experience than you. The first and second interview was ok with the hiring manager and few other teams members. But the third interview seemed like that interviewer was just asking basic questions about TCP from google.com. I bet that he was not that experienced fellow because I answered one of his questions with a quicker and faster solution but he didn't like it and said please explain to me the packet capture output. Hold on dude, whenever a customer calls you guys do you always do packet captures because the people who are calling you for support also are Tier2/3 network engineers, and they have already done all their initial troubleshooting. Therefore, when they call you for an issue there would be more questions about firewall features rather than you wasting their time on taking packet captures for no reason. I would recommend Palo Alto to get more experienced staff on the Technical interview panel. Anyways, I like the company and I use their products.
