What kind of questions (1st phone interview) should i expect?
I know blind is full of AWS SA interview Q&A, but the thing is a little bit different in my case, as this is a role where SA has to be part of telco domain.
Knowing telco processes? Deep technical knowledge of protocols etc? #interview #telecom #AWS
Want to see the real deal?

I can't give you advice on the interview but I can say I've worked with AT&T's network cloud solution. I worked upstream on openstack for my first 3 years in my career as a software developer so I was a big noob but this is what I've been able to pay attention to. They initially had a high interest in making repeatable deployments as quickly as possible so they had a large focus on tempalting configurations and layering for many kinds of data centers topologies with helm and openstack. The code is open source in openstack-airship. Every node deployment gave the department more money. You can find plenty of their talks on the openstack channel on youtube.
Beyond deployments they have a high focus on SR-IOV and DPDK for network throughput but this is intel specific technology working on their niantic nics.
One technology hurdle they have is integrating more than oneSDN controller with openstack/neutron so much they made their own project called gluon.
For network protocols you should know VLAN, VXLAN, QinQ. QoS networking is a nice to know. Monitoring and alerting in general. Virtual networking functions. Function service chaining.
I'm currently at CenturyLink but I have not been working on networking type of stuff except for the basics.
