How to Prepare for Campus Interview

A number of companies visit campus each semester to interview seniors for professional entry-level positions that start after graduation and current students for career related internships. Are you getting ready to leave your college and you are anxiously getting ready for your job search. Campus interviews can be nerve-wrecking for any student. Review the interview schedule, research company profiles, submit your resume to companies for consideration and sign-up for interviews.

There are many books as well as internet resources teaching Students on how to do job hunting and how to write resumes.The problem is, those books usually cater exclusively to those who have been in the working force for a while, and the college graduates or those seeking a job for the first time are for the most part ignored.This website will provide you with some tips for the upcoming college fresher’s. The interview tips given below are by experienced HR Experts. We hope that all …

How to answer - What are your greatest weaknesses?

Question 3What are your greatest weaknesses?
TRAPS:  Beware - this is an eliminator question, designed to shorten the candidate list. Any admission of a weakness or fault will earn you an “A” for honesty, but an “F” for the interview.


PASSABLE ANSWER:  Disguise a strength as a weakness.
Example: “I sometimes push my people too hard.  I like to work with a sense of urgency and everyone is not always on the same wavelength.”
Drawback:  This strategy is better than admitting a flaw, but it's so widely used, it is transparent to any experienced interviewer.

BEST ANSWER:  (and another reason it's so important to get a thorough description of your interviewer's needs before you answer questions): Assure the interviewer that you can think of nothing that would stand in the way of your performing in this position with excellence. Then, quickly review you strongest qualifications.
Example:  “Nobody's perfect, but based on what you've told me about this position, I believe …

How to Answer -What are your greatest strengths?

Question 2:What are your greatest strengths?TRAPS:  This question seems like a softball lob, but be prepared. You don't want to come across as egotistical or arrogant. Neither is this a time to be humble.
BEST ANSWER:  You know that your key strategy is to first uncover your interviewer's greatest wants and needs before you answer questions. And from Question 1, you know how to do this.
Prior to any interview, you should have a list mentally prepared of your greatest strengths. You should also have, a specific example or two, which illustrates each strength, an example chosen from your most recent and most impressive achievements.
You should, have this list of your greatest strengths and corresponding examples from your achievements so well committed to memory that you can recite them cold after being shaken awake at 2:30AM.
Then, once you uncover your interviewer's greatest wants and needs, you can choose those achievements from your list that best match up.
As a genera…

When does a programmer need to implement his own copy constructor?

      Though compiler automatically provides the default copy constructor, sometime a programmer needs to implement his own copy constructor. We can take up a case here:
       In the default constructor some memory allocation has been done for few data members and hence those will be created in the heap. In the destructor corresponding de-allocation code is there. Now if an attempt to copy an object is made, it won’t call the default constructor but it will call the default copy constructor which will copy the data member variable from stack and copy the pointers but won’t allocate any new memory space for the new copied object. So same pointers will exist in both the parent and copied object. This will not only create a great ambiguity but runtime error will occur when attempts will be made to delete both the objects. First object will get deleted properly. When it will try to delete the other object, the common pointer won’t exist and runtime error will come. Even if user stops the …

Does a class provide default Copy Constructor?

Yes! The default copy constructor is being provided automatically by the compiler if not implemented separately. In this, it puts the code for coping the data members and other variables that stay in stack. If something is being created by malloc or new in the heap, those are not being copied by the default copy constructor provide by the compiler.

In Java, what’s the difference between method overloading and method overriding?

The difference between overriding and overloading in Java is a common source of confusion – but it is fairly simple to understand. Let’s start the discussion by talking more about method overloading. Overloading in Java can occur when two or more methods in the same class share the same name or even if a child class shares a method with the same name as one of it’s parent classes. But, in order to actually have overloaded methods, the methods not only have to have the same name, but there are other conditions that must be satisfied – read below to see what those conditions are.
Suppose we have a class called TestClass which has 2 methods, and both methods have the same name – let’s say that name is “someMethod” – this would be considered to be method overloading if
 at least one of these 2 things is true:
1.) The number of parameters is different for the methods 2.) The parameter types are different. How to NOT overload methods: It’s important to understand that meth…

What is method overriding in java?

About method overriding: Overriding methods is completely different from overloading methods. If a derived class requires a different definition for an inherited method, then that method can be redefined in the derived class. This would be considered overriding. An overridden method would have the exact same method name, return type, number of parameters, and types of parameters as the method in the parent class, and the only difference would be the definition of the method.

Let’s summarize the differences between overloading and overriding. When overloading, one must change either the type or the number of parameters for a method that belongs to the same class. But, overriding a method means that a method inherited from a base class is what’s being changed.

Is the JVM (Java Virtual Machine) platform dependent? What is the advantage of using the JVM, and having Java be a translated language?

JVM translates bytecode into machine language Every Java program is first compiled into an intermediate language called Java bytecode. The JVM is used to both translate the bytecode into the machine language for a particular computer, and actually execute the corresponding machine-language instructions as well. The JVM and bytecode combined give Java its status as a "portable" language – this is because Java bytecode can be transferred from one machine to another.

Machine language is OS dependent Given the previous information, it should be easier to figure out an answer to the original question. Since the JVM must translate the bytecode into machine language, and since the machine language depends on the operating system being used, it is clear that the . The key here is that the JVM depends on the operating system – so if you are running Mac OS X you will have a different JVM than if you are running Windows or some other operating system. Th…

In Java, how does System.out.println() work?

This question is an excellent example of how just some very basic knowledge of Java can lead you to the correct answer. Most interviewers would not expect you to know the answer to do this right away – but would like to see how you think and arrive at an answer.

Marcus Aurelius once said: "Of each particular thing ask: what is it in itself? What is its nature?". This problem is an excellent example of how that sort of thinking can help one arrive at an answer with only some basic Java knowledge.

With that in mind, let’s break this down, starting with the dot operator. In Java, the dot operator can only be used to call methods and variables so we know that ‘out’ must be either a method or a variable. Now, how do we categorize ‘out’? Since println() is clearly a method, and its called using ‘out’, then we know that ‘out’ can not possibly be a method because it doesn’t make sense to have one method invoke another method with the dot operator in Java. This means ‘out’ must be a v…

How to prepare for interview? follow the steps.

Interview Preparation Research is a critical part of preparing for an interview. If you haven't done your homework, it is going to be obvious. Spend time researching and thinking about yourself, the occupation, the organization, and questions you might ask at the end of the interview.Step 1: Know YourselfThe first step in preparing for an interview is to do a thorough self-assessment so that you will know what you have to offer an employer. It is very important to develop a complete inventory of skills, experience, and personal attributes that you can use to market yourself to employers at any time during the interview process. In developing this inventory, it is easiest to start with experience. Once you have a detailed list of activities that you have done (past jobs, extra-curricular involvements, volunteer work, school projects, etc.), it is fairly easy to identify your skills.Simply go through the list, and for each item ask yourself "What could I have lear…
