SQL Interview Bonuses

Here are some more pointers to assist you succeed in your future SQL interview.

Learn as much as you can about your potential employer.

Not only for the SQL portion of the interview, but for the entire interview. It's critical to know everything there is to know about your future employer, their products, and their industry. When it comes to SQL questions, this is very crucial. What is the reason for this?

As previously said, the FAANG businesses will typically offer you very practical SQL code tasks that will require you to use the same data and solve the same difficulties that you will face if you are hired. Companies like the FAANGs aren't the only ones who do this. So, while you prepare for the interview, consider what information is crucial to this organization, how their database would appear, and so on. When practicing SQL questions, look for real inquiries from organizations you're interested in, or at the very least their competitors. If the companies are in the same industry, the data they utilize will almost certainly be similar. Here, check information about the pl sql developer job.

Prepare for a Whiteboard Session

On a whiteboard, you are frequently requested to write SQL code. Some people may find it shocking, which is understandable. You're probably used to writing code in a real RDBMS with real data, allowing you to test the query on a frequent basis. Even the most accomplished SQL gurus can't write code without first running it to see if it works or returns the intended result. The standards for the SQL interview, on the other hand, are a little more stringent.

It's understandable, even if it's frightening. Writing code on a whiteboard demonstrates that you understand how to write code. It's also crucial to read your (or someone else's) code. This is the ability that is tested on a whiteboard as well. Working with a real database and SQL environment will be easier for you if you can read a code and tell whether it will give you the desired result without relying on the database.

Make your code as clean as possible.

We're not referring to your handwriting here. If your handwriting is sloppy, there isn't much you can do. That does not, however, imply that your code must be unintelligible. When writing code, attempt to format it such that you and the interviewers can read it and check your solution more easily.

To make your code easier to read, utilize spacing and line breaks on a regular basis. If you need to (re)name tables or columns, use the same naming scheme every time. When necessary, add comments. When feasible, utilize aliases, but make sure they sound reasonable rather than random.
