First screening call, some simple OSPF, BGP and basic networking questions for roughly 40 minutes; then a couple leading principles questions, I didn't pass this first screening call so I can't give feedback on the "on loop" call of 5 hours.

Exeprience was good, interviewer was nice and made me feel easy but over all questions were in depth. I will definitely recommend everyone to apply and experience the interview process , I am sure you’ll learn something from the interviewer.
