Hi All
Below is the list of commonly asked questions during the interview for the position of AWS solutions architect or Cloud support engineer. ( Source: glassdoor.com)
I signed the non disclosure agreement, and therefore I can't write down all the questions. But know the basics of networking like TCP, UDP, routing protocols, and also how to troubleshoot a network. Know how ping and traceroute work etc. On the behavioral side, just be yourself. Show them that you can handle difficult situations, and give examples. While giving examples, don't say "we did", talk about what "you" did. Use "I" a lot.
Why Amazon
expliain 3 way handshake
Databases Concepts Networking Concepts Amazon Leadership Principles
Name a time you made a decision and the outcome was not what you expected?
Networking, Linux, Leadership principles

In what order are group policies applied in Active Directory?
DNS, Basic linux commands, Leadership principles and please go through all the interview questions from glassdoor, they were really helpful.
Explain DNS What is DHCP
how you reach to amazon.com, tell me layer vise. What is DNS? Explain all the steps for DNS. What protocol is used and how it is used to gate out from private network.(ARP)? website is slow how will you troubleshoot ? What is TCP? What is UDP? TCP three way handshake process. Basic l2,l3, some more networking, web servers, windows trouble shooting test, dns server questions. Why Amazon?
Onsite - 2 technical, 2 behavioral rounds. Technical - questions about DNS, DHCP process, TCP/UDP, entire stack and functions of each layer, Active directory, web servers, linux configurations, object oriented programming concepts. Some behavioral skills were also tested by giving some situations. Behavioral - Be ready to tell stories about your past work experience and projects to all the behavioral questions. They write down everything you say so be good at it. Leadership qualities are stressed the most. Handling conflicts, handling failures, misjudgement etc are some of the situations. Think over before you start answering. Also prepare for questions like why do you want to work with amazon? what do you want to do?
If a server failed to do a nightly backup, what could be a reason for that?
TCP/ IP Stack, DNS, DHCP, IP routing, troubleshooting scenarios

Finally, A bonus project to build a system that is robust and fault-tolerance for a start-up ecommerce website. .
Mostly ...tell me about a time when ... Technical questions were - DNS, how to resolve a deadlock, RAID0 and RAID1, linux boot up process etc. Many reviews submitted on this portal very extremely helpful.
Explain the DNS process of getting the IP addresses
1. What happens when you type amazon.com in the browser? ( was asked two times by different interviewers) 2. Phone interview was pleasant and the questions were troubleshooting issues 3. Database administration interview was tough for me. though the questions were simple i was not prepared for a DBA questionnaire. 4. Behavioral questions are pretty straight forward and the interviewers would like to know the experience of you in situations like challenging project/task. be prepared to what you have to answer. 5. Dont leave out to revise on the simple points such as common ports, DBA questions etc. 6. What and how the load value is calculated which is displayed when you give the command "uptime"?

Difference between TCP and UDP protocols, how would you design what is needed to host a website on the internet (a VPC and the different components you can use in AWS? Nope. Doesn't apply to this AWS job interview), how would you make switches and routers redundant (because there are switches and routers that you can configure and use in AWS, right?), what would you use to store files on a network (I mentioned AWS EFS but hey, no no... No discussion of AWS features on an interview for an AWS job role) how can you make a fault tolerance database (if you're thinking about automatic snapshots, nope. Read replicas in RDS you say? No AWS topics allowed), what are some of the code repositories available on the internet, what is containerization (don't you dare mention ECS, ECR) why use it instead of a virtual machine, what is the OSI Model, a question about continuous development (can't remember the proper term).

What's the difference between DNS TCP and UDP
I can not provided detailed information, but I recommend that focusing on Linux and networking basics, like Linux permission, file hierarchy system, TCP and UDP etc, don't waste your time on programming and scripting, just Linux and networking!

You must prepare well in basics even terms like TCP/IP window size and packet header. Must know Linux scripting, Active directory, LDAP, 'grep' command.
The engineer was very pleasant. He asked about FSMO roles in Active Directory, what are the aspects of setting up a VPN connection between two sites, what all happens when www.amazon.com is typed into a browser, and some basic firewall questions.
On-site, I met with a couple engineers, and several managers. These were a mix of technical questions (describe how you'd set up a network with three locations, what is a GPO and how is it applied in AD, etc) and soft questions (Tell me about a time when doing things the normal way didn't work, Tell me about a time you came up against a problem you'd never seen before, etc).
I thought the process was very thorough, but I never felt like I was being grilled. The people were all great.

The interview for Cloud Support Engineer at Amazon started with phone interviews. I went through 3 different interviews, all very technical, with just a few simple personality questions. The technical questions were around subjects related to networking: DNS, BGP, IP, HTTP and other. Questions were not tricky, and if you have general good knowledge of the protocols, then it shouldn't be hard. In my case, my knowledge was not that vast, and I didn't answer a few questions, just told an interviewer that I did not know the answer. Nevertheless, I was invited for additional interviews, and they were also of the same format, and questions were around networking too. After all the phone interviews (I think I had 2 or 3 total), I got an invitation for on-site interview in Texas. At that point, I declined the invitation since I got a different offer. Overall, if you have knowledge, I think interviewing (at least phone interviews) for entry-level positions is not difficult.
