A Perl Programmer is the professional who has done the specialization in the field of object oriented programming language i.e. Perl Programming. Perl stands for Practical Extraction and Report Language. It initially developed by Larry Wall in 1987 as a general-purpose UNIX scripting language to make report processing easier. It is basically a Script based language. This programming language provides powerful text processing facilities without the arbitrary data length limits of many contemporary UNIX tools, make easy manipulation of text files. It is also used for graphics programming, system administration, network programming, applications that require database access and CGI programming on the Web.

At this time, I am focusing on the sample of questions and their probable answers with which you will be encounter while facing the interview of a Perl Programmer.

1. Why you want to become a Perl Programmer?
Sir, it is one of the exciting branches of Computer Science in which I can able to program more effectively. It is the advance programming which uses many languages like C, shell scripting (sh), AWK, and sed. I can make an easy manipulation of text files through this Programming language.

2. What are the differences between C++ and Pearl Programming Language?
Sir, Pearl has an object whose data can’t accessed outside the class where as C++ has no such object. Pearl supports closures where as C++ doesn’t support any type of closure. Pearl is safe language where as C++ is not a safe one.

3. What do you mean by Scalar Data and Scalar Variables?
Scalar Data types are those which hold a single value and do not have any internal components. In computing, a scalar is a variable or field that can hold only one value at a time and it opposed the composite variables like array, list, record, etc. In some contexts, a scalar value may be understood to be numeric. In programming, a variable that contains only one value is known as Scalar Variables. A scalar data type is the type of a scalar variable.

4. Why Perl is one of favorite language among web developers?
Sir, it is a cross-platform, open-source computer programming language used widely in the commercial and private computing sectors. Perl is a favorite among Web developers for its flexible, repeatedly evolving text-processing and problem-solving capabilities.  It makes the report processing easier and smoother.

5. What are the ways through which we can express string in Perl?
Sir, we can express string in Perl through a regular expression repeatedly called a pattern. Pattern is an expression that describes a set of strings. They are usually used to give a concise description of a set, without having to list all elements.

I think, I have provided the basic knowledge about Perl Programmer.  Now, it’s your duty to answer as genuine as you can.
