You are a Python, BI, SQL, Java Script or other technology developer, and you are going to have a technical interview?

Chances are that 30-40% of the interview will be about SQL.

I've scoured a lot of sites in English and in French, to give you a summary of the most frequent questions during an interview.

SQL is now the most used language in the world. For information, Uber, Netflix, Airbnb use the SQL language.

Sign up for my course and leave for your interview with a clearer mind.

Here is a sample of the questions in my course:

• What is the difference between the HAVING and WHERE clause?

• What is an index?

• What is the difference between TRUNCATE and DELETE?

• What is STRING_SPLIT?

• What is the difference between OLAPand OLTP?

• Do you know the ranking functions ?Could you give me a example?

And many other questions, which will allow you to leave more confident during your next interview.

Important points about this course:

• This course covers all SQL Server versions, even SQL Server 2019.

• I made sure that the videos are not too boring, and that they do not exceed 10 minutes.

If you really want to become proficient in TSQL, frankly you won't find anywhere else a course as thorough as this one, I can guarantee it!
