I’ll be honest this was one of the hardest interviews I’ve ever been on in my entire life. It was kind of brutal. So there are 4 interviews in total. The first interview was basically a phone call and they asked 10 basic questions(DNS, Proxy, IPS/ids, TCP/ip) then you talk with a senior recruiter for the 2nd round interview. They will ask behavioral questions like how do you handle failure, tell us about a time you had a difficult situation and handled it. The third interview was technical and pretty much went deeper into what the 1st recruiter asked you. Everything that first recruiter asked you STUDY for!! Now just when you make it past this round thinking you’re home free, you get a 4th and final interview by managers. Now this was by far the hardest interview I’ve probably ever been a part of. They asked extremely technical questions to see how far you can go ! Put it this way I answered 90 percent of the technical questions on the third interview but couldn’t answer 1 on the 4th. This was a mix of technical and why do you wanna work here questions. By far the last interview is the one that really matters. If you do really one the first 3 that’s great! The last one is what counts. So don’t get your hopes up.
