It seems fine towards the expirienced guys, Need to be very Precise with the Networking Knowledge, More towards the Knowledge from L4-L7. The process is pretty simple. You need to just be ready to get questions from Your Past expirience and as per the Live scenarios. This is a Senior Position so be ready to get overflow with scenario and indepth questions.

Interview process is simple, the interviewer and engineer are professional. They have handled it professionall. But I think a feedback email if Not selected would have been much better here. I have followed up 6 times and the TA HR just says she doesn't have an update yet.
