High Difficulty PHP and SQL Test

Seven coding problems and no multiple-choice questions. Five are solved in PHP (histogram, longest streak, X pattern, minimum-sum path through a 3 x 3 grid kept in a one-dimensional array, and sorting blocks of numbers separated by zeros) and two are SQL queries. The time limit is 120 minutes, at hard level.

It is meant for cases where a basic PHP check is not enough. Basic PHP Test + SQL is the entry-level option. The report places the candidate in a programming skill band, from low to very high.

What it measures

• Building a histogram and finding longest streaks in PHP

• Printing an X pattern of any size in PHP

• Finding the lowest-sum path through a grid kept in a one-dimensional array

• Sorting each block of numbers inside an array split by zeros

• Writing SQL queries that group employees by department and relate people to their education level

Ideal for

PHP developers with strong skills, back-end roles with PHP and SQL and selections where only strong programmers should move on.
