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
Expect everything from a telco perspective and more. Treat it like an interview with any other company aside from the leadership part. Get ready for tough leadership questions for SA. Prepare your scenarios, it is likely 2 or 3 LP questions will be asked at the end of the interview.
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.
Finally, another network Engineering person from CenturyLink. I thought we had become a dying breed on Blind.
I do software development on cam.ctl.io and monitoring.cam.ctl.io now
they will ask similar SA questions about system design and. leadership principles "design netflix" kinda questions with expectation of you explaining with more ccna level terms
Use donnemartin's GitHub for system design primer
Just a guess, but read up on Telco network architecture and different terms used.
Yes, there are telco models, which one should know
Also interested, have an interview coming up for the same role
When do you have the interview?
Tomorrow
Interested to know. How was it? Anything you can share??
I think he can share more detailed way when he gets the offer. now we are all potential competitors
You got offer by now?
Offered, promoted and pip’d
You mean they gave you an offer, then promoted you, and then put you in a personal improvement plan? In how much time?
How was it? Can you share?
