That much I can recollect in the technical Written.

They told that written test results will be announced in the evening and the candidates who got selected will be called in the evening. The next three level of interview will be conducted on Monday as the written test was conducted on Friday.

I done the technical section well and had the hope that I will clear written if they consider technical knowledge. My hope came true in the evening. I got the call that I was short listed in the written test and have to attend second round which is fully technical on Monday.

As it is Saturday and Sunday I prepared well in Core Java and Some what in JSP, Servlet and EJB.

On Monday I was asked to be there at 10.00 AM. I went there by 9.50 A.M. I have been waiting in the reception still 11.00 A.M as those people where busy with some training program in their concern. At 11.15 the Hr came and collected our resume and said that all the interview panel where in conducting interviews for other positions. So she asked us to wait.

In 5 minutes the first person was called in. In another 5 minutes the second person was called in another panel. Nearly 1 hour it went neither of them came out . Before Lunch they called only 3 guys. And they asked others to leave now and come at 2.30 PM after having lunch.

At 3.15 I was called in

INTERVIEWER: Please take you Seat.

ME: Good Afternoon Thank you.

INTERVIEWER: Good Afternoon (she didn't asked any other questions and directly started Technical Questions). What is mean by class?

ME: Class is the structure and Behaviour of objects or Set of Objects. Class is a logical Constrain. Memory is not allocated to Classes.

INTERVIEWER: How can you access the class?

ME: By creating Objects to the class

INTERVIEWER: What are the Access Specifiers?

ME: Public, Protected, Private,

INTERVIEWER: What is inheritance?

ME: Inheriting the characteristics of base class to derived class. Like Fathers Behaviour is inherited to child

INTERVIEWER: Difference between Final, Finally and Finalize?

ME: Finally is the block used with exception handling. The code provided in the finally block is need to be executed compulsory in spite of exception caught or not. Final is a keyword declared with variables, class and methods. Final variable act as Constant, Final class cannot be inherited, Final method cannot be overridden. Finalize is the method called when object memory is need to be de allocated.

INTERVIEWER: What is Abstract class?

ME: The class is to be declared with abstract keyword. At least on of the Function is to be declared abstract 1.e the method is to be declared and do not contain any definition. We cannot create object for abstract class. This class is to inherited in some other classes and the methods are to be overridden to have the definition.

INTERVIEWER: What are the Difference between String and Sting Buffer?

ME: String is immutable and String Buffer is Mutable. I explained it with a Example in the sheet provided to me.

INTERVIEWER: What are the Difference between Servlet and JSP? (My toughest part Started)

ME: When come to coding Part, In Servlet we need to have HTML Tags in JAVA Coding and In JSP the Java coding are need to be embedded in HTML Tags. For providing large amount of Dynamic content we can go for Servlet, if we consider presentation the more important then we can use JSP. In Translation Page the Tags are converted to Servlet. (That much I know about it. Thank god she didn't ask me write code in JSP).

INTERVIEWER: Various Stages of Thread lifecycle?

ME: New, Runnable, Running, Blocked, Dead.

INTERVIEWER: What is the Life Cycle of Servlet?

INTERVIEWER: What is array list and how you add element in array list?

ME: The Array List class extends Abstract List and implements the List interface. Array List supports dynamic arrays that can grow as needed. Add () is used to add elements to arrays.

INTERVIEWER: What is iterator?

ME: Sorry madam I don't know.

INTERVIEWER: Difference between hash map and hash set?

ME: Hash Set extends Abstract Set and implements the Set interface. It creates a collection that uses a hash table for storage. The advantage of hashing is that it allows the execution time of basic operations, such as add ( ), contains ( ), remove ( ), and
Size ( ), to remain constant even for large sets. The Hash Map class uses a hash table to implement the Map interface. This allows the execution time of basic operations, such as get ( ) and put ( ), to remain constant even for Large sets.

Actually I just told what I knew. This is not the difference


ME: EJB are the server side Components that specifies the building enterprise level, distributed application in java.

INTERVIEWER: What are types of EJB tell me some thing about the Types.

INTERVIEWER: Asked to write SQL Quires for SELECT, UPDATE, and DELETE

ME: I did it in the paper.

She also asked some other questions. Even though I answered most of the question I am not confident I get selected because I answered the questions very fast flow of speech. She told Ok you can go. We will call back latter, After hearing this I lost my little bit confidence because those who cleared second round were asked to wait for third round in the spot it self. So I left the area immediately.

As home is near by I reached home. In a ten minutes I got a call from the Company and asked me why I left immediately, you have to attend the third round as you cleared the first round. I was happy and also tensed that I did some wrong things in my tension, that I should not been left that place immediately. I asked sorry to him in phone and told that I will be there in 10 min and reached to the company on time.

I did the program correctly and there were few mistakes he told the wrong and I asked sorry and told the solution to the wrong lines. Then he asked me to wait for the HR Interview. After Some time I was told to attend HR interview on the next day morning at 11.00AM
