Laravel 5 Interview Questions

This is a compiled list of Laravel interview questions. If Laravel is an engineer's PHP framework of choice, they definitely have potential to be a good candidate, but a lot of new PHP engineers have been into Laravel too. The framework itself is very welcoming to newcomers, which makes it easy for beginners to feel that they know more than they really do.

General Questions

This question can help decide what level of questions to ask.

These are the tasks you might encounter in your PHP/Laravel job interviews:

Coding exercises: These may involve solving programming problems using PHP or other relevant languages, implementing algorithms, or working with data structures.
API design and implementation: You might be asked to design and implement APIs to meet specific requirements or integrate with existing systems.
Database queries: You could be given tasks that involve writing SQL queries to retrieve or manipulate data in a database.
Framework-specific tasks: You may have tasks to work with Laravel.
