Interview Questions

A library of container templates approved by the ANSI committee for inclusion in the standard C++ specification. A programmer who then launches into a discussion of the generic programming model, iterators, allocators, algorithms, and such, has a higher than average understanding of the new technology that STL brings to C++ programming

Most recently, we had a new hire (Prakash) that was really struggling with getting to work on time, and I knew the boss (Dan) was getting irritated. Over lunch one day I explained to Prakash how important it was to our boss for everyone to be there at least 10 minutes early. It was personal with the Harry, but you could really get on his bad side when you were frequently late. The new employee was grateful for the advice. At his previous employment, the boss was only concerned about the work getting done on time; he/she did not "watch the clock".

PHP supports single level inheritance.

Inheriting a class would mean creating a new class with all functionality of the existing class in addition to some more. The created class is called as a subclass of the parent class. Parent is a keyword which we use to access members of a parent class. Inheritance is usually defined by using the keyword “Extend”. $this is used a reference to the calling object. Inheritance avoids redundancy of code.

Example:

Class employee extends manager : Here Employee is a subclass of manager.

Echo $this->name can be used to echo variable name of the parent class.

The best way to respond to the interview question "What are your goals for the future?"

Don't discuss your goals for returning to school or having a family, they are not relevant and could knock you out of contention for the job. Rather, you want to connect your answer to the job you are applying for. Examples of good responses include:

=> My long-term goals involve growing with a company where I can continue to learn, take on additional responsibilities, and contribute as much of value as I can.

=> I see myself as a top performing employee in a well-established organization, like this one. I plan on enhancing my skills and continuing my involvement in (related) professional associations.

=> Once I gain additional experience, I would like to move on from a technical position to management.

=> In the XYZ Corporation, what is a typical career path for someone with my skills and experiences?

A UNION query combines the output from multiple queries and must include the same number of columns.
