Don't regurgitate google returns for SQL questions. Know enough to put it in your own words, even if it's not text book perfect it is more impressive than a verbatim search result. Also, it helps to know the different flavors of SQL and what their differences are. T-SQL, Postgresql, and Oracle are the big three but having general knowledge of others can also be impressive to an interviewer.

Gain a basic understanding of cryptography and its mechanisms. Study common vulnerabilities and how enterprise antivirus solutions operate. Additionally, familiarize yourself with security governance principles.

Understanding the vision of the software applications' purpose, problem to be resolved, audience of users, platform running the application, whether the software will be for an opensource project or closed are basic first questions. These days with AI in our world, even in it's narrow state, a discussion with an LLM will set the direction to begin the development and provide essentially the startup operations team; configure the development environment, and launch the business application to perpetuate a marketing strategy direction to generate revenues.

Problem Understanding: Grasp the problem thoroughly before starting development. SDLC Model: Learn the Software Development Life Cycle (SDLC) to understand the stages of software development. Coding Skills: Practice writing small functions and combining them to build larger applications. Interview Preparation: Expect questions from these areas. Knowing how to code and understanding the logic will help you answer effectively.

Once you check everything into git you can then change one variable at a time. It doesn't matter if you are setting breakpoints and debugging or making educated guesses if you effectively track all changes. Eventually you will debug or guess your way to victory. Tagging and branching can ensure that experimental changes can't affect production. Cherry picking hunks using git add -p is the most valuable skill I know of. It prevents conflicts, reduces the time to merge, but it also doesn't stifle experimentation because local hacks can live forever as long as they are in their own hunk.

You can expect question on these tools, if you tell these tools are the area of your expertise. Please have a great understanding of data warehousing and business intelligence.

I think SQLite is the best tool out there because you can prototype an ETL from CSV to a pretty spreadsheet or send it right into R. It can be idempotent, fast, and accurate once you optimize the indexing and PRAGMA statements. The allows me to rapidly develop what I need to do. You can autogenerate a spreadsheet with graphs with python or send the data into R and use "car" from "cran" to get many types of graphs. All of this can also be automated with a script so every time the data changes a CI/CD pipeline can regenerate artifacts. Over time you can expand the views and improve the indexes. Simple but effective analysis can help stakeholders make decisions faster with "just in time" ETL that's integrated into the CI/CD pipeline.

As you prepare for your cloud computing interview, it’s crucial to have a solid understanding of basic cloud concepts and how cloud computing works.
