AWS Telecom Solution Architect Interview

Apr 27, 2020 37 Comments

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

    Umm I can't really say anything about AWS because I worked in the OpenStack part of things. The public cloud initiative was ramping up as I left. Sorry if this is a waste of time.

    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.

  • I'm the author of the post, had two interviews, first one technical where question go almost everywhere. Networking, storage, hyperscale, devops, architecture, you name it. Not super detailed answers expected but knowledge of all that is a must. Then one behavioral with hiring manager, one technical assignment and finally the five ours interview all in leadership principles. It has been a great experience to have a career retrospective to prepare for it. Got called by hr today that they will make an offer by tomorrow.

    • Thanks for sharing. 5 hours of leadership principles was technical or non technical? for ex. when you explain a situatuon that you showed leadership, do they go deep on the technical details of it?

    • Yes it can start with leadership principle and diving deep can bring to technical details. Focus on 14 LP and check Dan croitor on YouTube, his free videos were helpful
