Data Architect Interview Questions

"Data architects design, build, and maintain the systems that dictate how a company's data is collected and stored. Expect interviews to consist primarily of technical questions that will test your knowledge of engineering databases. Employers are often looking for candidates with degrees in data science, computer science, or another related field, as well as a knowledge of relevant database languages like SQL."

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).

A lot of behavioral based questions, including "Tell me about the biggest mistake you've made professionally and what you learned from it," and "Tell me about a time you had to make a decision with incomplete data - what was your decision, and what would you do differently if you had to do it again?"
