Object Oriented Interview Questions
This is the entry page into the OOPortal Interview Questions Sitemap.
Click on a link to the left to examine the specific area of object technology.
Object Oriented Programming (OOP) is a programming paradigm based on the concept of "objects", which are data structures that contain data,
in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods.
A distinguishing feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of "this"). In object-oriented programming, computer programs are designed by making them out of objects that interact with one another. There is significant diversity in object-oriented programming, but most popular languages are class-based, meaning that objects are instances of classes, which typically also determines their type.
Now I want to share something important with you. For those of you new to IT/Technical or any other job interviews, the process can seem overwhelming Interviewers throw questions at you, expect you to whip up brilliant algorithms or
Program Codes on the spot, and then ask you to write beautiful code on a whiteboard luckily, everyone else is in the same boat, and you’re already working hard to prepare Good job! So, throw the ball back in the interviewer’s court.
Always Write your Code on Paper:
Most interviewers won’t give you a computer and will instead expect you to write code on a whiteboard or on paper To simulate this environment, try answering problems by writing code on paper first, and then typing them into a computer as-is whiteboard. Paper coding is a special skill, which can be mastered with constant practice. I mean suppose your thoughts are the interviewer and your mind is the compiler
First Know Your Resume:
First at all, I want to share something important thing with you that you don’t know. I am
talking about differences. Yes, the Difference between, A CV (Curriculum Vitae) and resume. Curriculum Vitae is a document prepared
by students searching a job. It provides the academic details of the student, another hand a resume is prepared by the experienced professionals, which emphasizes job history and on-the-job skills and experience. While technical skills are extremely important, that’s no reason to neglect your own resume make sure to prepare yourself to give a quick summary of any project or job you were involved with.
Interviewers want to understand how you think and approach problems, so talk out loud while you’re solving problems let the interviewer see how you’re tackling the problem, and they just might guide you as well.
In my years of interviewing at IBM, I saw some interviewers ask easy questions while others ask harder questions but you know what? Getting the easy questions doesn’t make it any easier to get the offer Receiving an offer is not about solving
questions flawlessly, but rather, it is about answering questions better than other candidates. I am
excited for you and for the skills you are going to develop thorough preparation will give you a wide range of technical and communication skills It will be well-worth it no matter where the effort takes you For Entry level jobs, the IT industry requires students and young professionals with good programming, especially the world most demanded Java language and
problem solving skills. For jobs that require programming skills most of the IT companies look for candidates with good C, C++ (lesser extent) and very specially Java Programming Skills.
