Let's face it; no one likes the interview process. Well, certainly not the people being interviewed anyway. You have to be on your best behavior, you only get one chance to get it right, and it's like taking your driving test all over again. Over the years I've been to countless interviews. To get my first job out of college I attended some 15-20 interviews a week. Whether it was in Britain or over here in the States, the questions never really seemed to change from job to job. Not only that, but the answers to them are usually the same, with your own personal interpretation of course. Here I present 23 questions you're likely to be asked, and how I have learned to answer them. Why 23? Because I had more than 20 and less than 25. Remember, being interviewed is a skill, and if you do the preparation you should ace it every time. (See also: 12 Unique Ways to Score a Job Interview)

Gosling's goals were to implement a virtual machine and a language that had a familiar C-like notation but with greater uniformity and simplicity than C/C++. The first public implementation was Java 1.0 in 1995. It made the promise of "Write Once, Run Anywhere", with free runtimes on popular platforms. It was fairly secure and its security was configurable, allowing for network and file access to be limited. The major web browsers soon incorporated it into their standard configurations in a secure "applet" configuration. popular quickly. New versions for large and small platforms (J2EE and J2ME) soon were designed with the advent of "Java 2". Sun has not announced any plans for a "Java 3".

Personal interview questions and answers

What was your biggest mistake?


There’s nothing wrong in admitting a mistake. A human being is bound to commit mistakes. This time it is advantageous to go back as far as possible in the past and find an answer.

The advantage of doing this is that a youngster is expected to commit more mistakes than a mature and seasoned person. This would give an impression that since that time you have committed mistakes but not that big.

Personal interview questions and answers

HR interview questions and answers for senior executives

1. Assuming that you are selected, what will be your strategy for next 60 days?

If I am selected for this position, I’ll use my initial 60 days in understanding my role carefully in terms of the contribution to the business and increasing the overall profitability. I’ll sit with my line manager and other juniors to understand what has already been done and what its impact has been. From there on, I’ll formulate my strategy to growth in close conjunction with managers and see that it is properly implemented.
 

2. How would you improve upon our product/ company?

Since I’d be coming from an altogether new environment, I am bound to possess a new perspective towards everything here including the company, product, customers, environment, strategy etc. This will enable me to constructively question things which anyone else here might not do. This will help in improving the things and making the product & company better.
Having worked closely with product development team I understand how the research for product development is carried out and how is customer requirement analysed; I’d be able to provide a value addition there too.

Start with the item farthest back and work up to the present.
2. Why did you leave your last job?
Stay positive regardless of the circumstances. Never refer to a major problem with managementand never speak ill of supervisors, co-workers or the organization. I f you do, you will be the onelooking bad. Keep smiling and talk about leaving for a positive reason such as an opportunity, achance to do something special or other forward-looking reasons.
3. What experience do you have in this field?
Speak about specifics that relate to the position you are applying for. If you do not have specificexperience, get as close as you can.
4. Do you consider yourself successful?
You should always answer yes and briefly explain why. A good explanation is that you have setgoals, and you have met some and are on track to achieve the others.
5. What do co-workers say about you?
Be prepared with a quote or two from co-workers. Either a specific statement or a paraphrase willwork. Jill Clark, a co-worker at Smith Company, always said I was the hardest workers she had ever known. It is as powerful as Jill having said it at the interview herself.
6. What do you know about this organization?
This question is one reason to do some research on the organization before the interview. Find outwhere they have been and where they are going. What are the current issues and who are themajor players?

8. Are you applying for other jobs?

11. What kind of salary do you need?
A loaded question. A nasty little game that you will probably lose if you answer first. So, do notanswer it. Instead, say something like, that,s a tough question. Can you tell me the range for thisposition? In most cases, the interviewer, taken off guard, will tell you. If not, say that it can dependon the details of the job. Then give a wide range.
12. Are you a team player?
You are, of course, a team player. Be sure to have examples ready. Specifics that show you oftenperform for the good of the team rather than for yourself is good evidence of your team attitude. Donot brag; just say it in a matter-of-fact tone? This is a key point.
13. How long would you expect to work for us if hired?
Specifics here are not good. Something like this should work: I,d like it to be a long time. Or As longas we both feel I,m doing a good job.
14. Have you ever had to fire anyone? How did you feel about that?
This is serious. Do not make light of it or in any way seem like you like to fire people. At the sametime, you will do it when it is the right thing to do. When it comes to the organization versus theindividual who has created a harmful situation, you will protect the organization. Remember firing isnot the same as layoff or reduction in force.

Top 20 Java technical interview questions and answers for experienced Java developers

Q1. Can you describe the high level architecture of the application that you had worked on recently? or Can you give a 100 feet bird's eye view of the application you were involved in as a developer or designer?

A1. The purpose is to judge your overall experience. Here are a few links that will prepare for this most sought-after question, especially for the experienced professionals.

  • 3 to n-tier enterprise Java architecture, the MVC-2 design pattern, the distinction between physical and logical tiers, and the layered architecture.The logical tiers shown in the diagrams for the above link are basically layers, and the layers are used for organizing your code. Typical layers include Presentation, Business and Data – the same as the traditional 3-tier model. But when  talk about layers, we’re only talking about logical organization of code. Physical tiers however, are only about where the code gets deployed and run as war, ear or jar. Specifically, tiers are places where layers are deployed and where layers run. In other words, tiers are the physical deployment of layers.
  • high level architectural patterns and the pros and cons of each approach. Discusses a number different architectual styles like MVC, SOA, UI Component, RESTful data composition, HTML data composition, Plug-in architecture, and Event Driven Architecture (EDA). Also, covers a sample enterprise architecture, which is a hybrid of a number of architectural styles.
  • Single page web design. A single rich web page loading different sections (e.g tabs) of the page by making different ajax calls to relevant RESTful web services to get the JSON data to render the relevant sections.
  • Understanding of various types of application integration styles. Enterprise applications need to be integrated with other systems, and this post covers different integration styles like sharing the same database, feed based, RPC style (e.g. web services), and exchanging JMS messages.

Java Basics - Interview Questions and Answers

37. What is the common usage of serialization?
Whenever an object is to be sent over the network, objects need to be serialized. Moreover if the state of an object is to be saved, objects need to be serilazed.
38. What is Externalizable interface?
Externalizable is an interface which contains two methods readExternal and writeExternal. These methods give you a control over the serialization mechanism.
Thus if your class implements this interface, you can customize the serialization process by implementing these methods.
39. When you serialize an object, what happens to the object references included in the object?
The serialization mechanism generates an object graph for serialization. Thus it determines whether the included object references are serializable or not. This is a recursive process.
Thus when an object is serialized, all the included objects are also serialized alongwith the original obect.
40. What one should take care of while serializing the object?
One should make sure that all the included objects are also serializable. If any of the objects is not serializable then it throws a NotSerializableException.
41. What happens to the static fields of a class during serialization?
There are three exceptions in which serialization doesnot necessarily read and write to the stream. These are
1. Serialization ignores static fields, because they are not part of ay particular state state.
2. Base class fields are only hendled if the base class itself is serializable.
3. Transient fields.
42. Does Java provide any construct to find out the size of an object?
No, there is not sizeof operator in Java. So there is not direct way to determine the size of an object directly in Java.

MBA calling: How to prepare for the personal interview

Though there is no dearth of articles on interview etiquette, there is an actual shortage of good articles on the most crucial factor in an interview -- the interviewer's questions and your answers. Many problems candidates have include nervousness and stammering in an interview, which is directly related to the candidate's unfamiliarity with the questions and a general lack of preparation.
TCYonline.com experts present for the readers of Rediff.com, a few of the most commonly asked interview questions. There are no ready-made answers to the questions, instead, the attempt is to try to help you arrive at the correct answer yourself, so that you sound natural and coherent in an interview. Ultimately, an interview is a mirror to see your inner self and a subjective, specific and honest presentation is the key to success. 
Q.  Tell me some thing about yourself.This is how most interviews begin and this is one question you cannot afford to be unprepared for.
To frame a good answer it is always helpful to know what is it that the interviewer wants to know about you. An interviewer would like to know.
~ Your educational background~ Your work experience, if any~ Your strengths and achievements
~ About your family background
~ About where you are coming from academically, professionally
You should be short and crisp about all the points mentioned above. If the interviewer needs an elaboration s/he will ask you.
