Need advice on job interview as backbone engineer.

I work with ISP whose backbone is built on Junos.

And a NOC engineer I have been working on IPTRANSITS,MPLS,BGP DIA ETHERNET etc.

For the role of BACKBONE ENGINEER what questions should I expect in the interview ,as have been loosing confidence due to current pandemic situation and suffering from depression and anxiety which has been hindering with my career growth.

I am revising the concepts but it would be a confidence booster to hear all the awesome professionals here.
