Here is a list of php question areas that might be asked in an add-hoc oral technical interview.
First of all they will focus on some more basic questions,
- Difference between GET and POST
- Echo and print
- Language constructors and so on…
Then most likely they would focus on,
- The behaviors of sessions and cookies
- Ways of a session ID can be passed
- Db connection strings and how can it be centralized and stuff like that.
- Difference between normal connection and a persistent connection etc..
Then obviously the interviewer will have to asses on your knowledge in Object Oriented Programming techniques,
- Simply what is a class or object?
- Some definitions on OOP techniques like, Encapsulation, overloading, inheritance.
Also design pattern questions will be asked here.
- Which OOP pattern implements a class that must be instantiated only once in a life span of a script?
- Some more questions on design patterns mostly real world scenarios.
- How design patterns can be used as a mix of more than one pattern?
- Some more discussions related to MVC, Abstract factory, and singleton.
Last but not least they will focus on your knowledge about the security issues, best practices, probably about register global issues and so on. Then the interviewers will focus on more into your CV and about the Frameworks and CMS’s you have been exposed to.
We will be discussing all of above points one by one in later posts stay tuned.
Cheers !
