Successfully navigating this phase involves not only meeting the basic job requirements but also showcasing cultural fit and a genuine understanding of Amazon’s guiding principles.

Some more Technical Questions-

Question: Explain the purpose of a DISTINCT clause in SQL.

Answer: The DISTINCT clause is utilized to retrieve only unique (distinct) values from a query result.

Question: Compare and contrast UNION and UNION ALL in SQL.

Answer: The UNION operator extracts distinct rows from the queries specified, whereas UNION ALL retrieves all rows, including duplicates, from both queries.

Question: How do Window Functions operate in SQL?

Answer: Window Functions perform calculations at the row level with a set of related values. Unlike aggregate functions like SUM(), window functions don’t consolidate the rows into a single value; instead, they return output for each row.

Question: Differentiate between a primary key and a foreign key in a database.

Answer: A primary key is a column or set of columns in a table that uniquely identifies rows in that table. On the other hand, a foreign key is a column or set of columns in a table whose values correspond to the primary key values in another table.

Question: Explain the distinctions between the SQL functions LEAD and LAG.

Answer: LEAD provides values from rows occurring after the specified row, while LAG provides values from rows occurring before the specified row.
