Initially they send a pcap and I need to provide analysis of the pcap, whether there is any issue, what would be, how to solve it. they are satisfied with my answer, they proceed with phone interview, apparently I said things that they didn’t expected, hence they asked me to come in Amsterdam office for the final interview. The final interview was pretty interesting and for sure intensive. it was divided in 3 session. 1. the Management session: where one of the manager kept reminding me that his technical people will do stress test on me..they will ask question starting from easy ones to the most difficult one until I break the keep on repeating don’t worry we will break you, we want to know my breaking point. Somehow this repetitive message was kinda intimidating as I didn’t really prepared technically and at the time I was doing more security related work than networking related task (hence I felt I was not 100% up to date on my networking knowledge and I have already forgot many things that I used to know well) 2. the Networking interview: Indeed it was very deep, however I ended up having an "argument" how OSPF really works.. Definitely the most deep technical interview I have ever done. 3. the security interview: this part is more related to security in networking as oppose to security in general of specific platform/OS/application. Again it was very technical and this time I have to say they interviewer are more friendly.. It was nice relaxing interview, but still very challenging. Working in juniper now, I realize why in average people here are very very technical oriented, even the sales engineers where in other vendor are more sales/marketing.. in juniper are very technically savvy people. the selection is very tight, not only the candidate must fit in the team & open but must have very strong technical background & willing to developed their technical skill.
