The sixth commonest question asked at SQL interviews
You could be asked to write an SQL query that would help you find how many employees who are born between two given dates and then differentiate them as per gender as well.

The eighth commonest question asked at SQL interviews

The ninth commonest question asked at SQL interviews
You could also be asked in an SQL interview to find all employee records that contain a certain word, say SAM. In this case, there are normally no restrictions regarding the case of that particular search query. The answer is SELECT * from Employees WHERE UPPER (EmpName) like '%SAM%';
