Description
Is your goal to get good at SQL Server interviews? Then you are on the right track.
People who work in SQL Server and people who pass SQL Server interviews are two different things. People who work with SQL Server usually do the same things over and over again, like backups, custom reporting, and so on. Simple questions like “What kind of triggers are there?” make them a little hesitant, so this is why.
Because they need to make some changes, they don’t know the answer. That’s what this class does. I can get ready for the SQL Server interview in just a few days thanks to this app.
Below is a list of questions with the answers, demonstrations, and detailed explanations for each one, so you can learn more. Having fun with your education is a good thing. I hope you have a good time looking for work.
