Java Interview Preparation (specialization course in Java) ?

Question: Is there any specific field or course of java which needs more focus in point of interview ?  any other course which add or enhance  my skill of  java knowledge?

By Praveen Sahu From Oriental Inst. Of  Sc. & Tech.  Bhopal

Answer: Yes, there are some specific fields in java which need to be concentrated according to me which are given below:


For Freshers:



(a) Command Over All Core Java Topics like OOPS concepts,class, objects, keywords, access specifiers, platform in dependency of java etc. It is also known as basic java, or you can say except java beans, swing, applet, servlet, jsp and ejb everything is very-very important for the java  interview point of view  for freshers.There is an online certification from sun micro systems(the creator of java) i.e SCJP , Sun Certified Java Professional, if you clear this exam then you have a big market in IT industry, there are so many people who might have this certification from various institutes who take some money and give certificates, please don't compare yourself with these people.


Praveen , again I want to repeat, you are a fresher, you don't need these certification and no need to waste your money on money eater institutes, your parents are supporting you for MCA from a respected college, just show them that you can get a good job on the basis of your degree itself, yes you can , just follow the steps I suggested you when I met you in Bhopal, or you may read my following post:This post includes the tips I gave you with best institute for .Net project in Delhi/Noida.

But if you still want to prepare for this specialization course (SCJP) then follow my below best suggestions, I guarantee you will definitely clear this world renowned online java certification without paying anyone any money:


(i) First you complete "Java For Beginners By Shirish Cahavn" by shroff publishers and distributors, this book is written by Mr. Chavan , I really loved to read his simple yet excellent way of teaching java.


(ii) Now you read "Head First Java" for Core Java  by O'reilley publications.An another excellent book written by creator of SCJP certification papers form Sun Micro Systems Inc.


(iii) Now complete "SCJP guide by Khalid Mughal", a very famous name among java lovers for clearing SCJP.


Please do follow the steps , read these books in the sequence I have suggested you.


(b) C++  Vs.  Java ? Java security features ?


(c) J2EE Vs .Net ?


(d) How to implement data base features using java, jdbc and basic sql queries not oracle or sql  server ?


For Experienced People:


(a) Excellent command over the project doing in previous company be it just JSP or struts , hibernate or spring.


(b) If you are from non IT experience then please try to have perfect command on core java concepts and here I will suggest you try to get SCJP certification being an experienced person from no IT background , but due to some reason want to join software company.


Please remember for Java based interviews please don't waste your time on applet and swing and ejb (for freshers, just need to know what is ejb, advantages of it etc , no much details) but experienced need to know details of  servlet, jsp and ejb.


This is all from my side and would like to hear more from  my Krantikari (Er. Praveen Sahu) with whom I want to fight for my India for our mission "No Youngster of India Will Be Without Job And Will Never Feel Frustrated, Helpless or Alone"..

C Interview Questions and Answers ?

Question:

WHAT TYPE OF QUESTIONS TO PREPARE IN C LANGUAGE FOR INTERVIEWS ? By Kunjal Rathod from RCET Bhilai.

Answer:

First of all let me make sure why you just want to prepare for c interview questions ?well if you are not sure about this question then let me tell you one thing that in technical interviews c and c++ questions are asked together not just c or c++.

If you are not able to answer interviewer's questions then they ask you that tell us on
which language you are good at if you say c then they ask you c based questions only if you say c++ then they ask you c++ questions only.

So if you trust me I am going to suggest you how you can prepare for both c and c++.

Please follow these steps:

(1)Solve all the exercises of "let us c" and "let us c++" by kanetkar, if you have less time for the interview then make sure to complete "let us c" by kenetkar.

(2)If you are financially good then buy these two books by BPB publications:

(a)Interview Questions In C Programming.(around 400/-)
(b)Interview Questions In C++ Programming.(around 400/-)

(3)If you are not financially good then follow these steps:

(a)Just go to http://www.coolinterview.com/type.asp?iType=40.This web site is having huge collection of c interview questions with answers with no sighn up required.Just make sure that don't go to other sites from this site rather just try to concentrate with c questions and answers.Another thing is that on this site you may get 2-3 answers for a single question now its up to you to take the right one but if you can't make sure which one is the best answer then please let me know by asking at http://besthelponweb.blogspot.com

(b)After completing above web site you can now check out http://www.newinterviewquestions.com/cat/C-interview-questions/?&iType=40&iDBLoc=0 Here also you get huge collection of c interview questions, you might get same answers as above site but this is just a reference for you,please don't get confused and try to make out your own answer from these two sites or if you are really very confused with some answers from both the sites then please feel free to ask at http://besthelponweb.blogspot.com

(c)Now you can check out http://www.techpreparation.com/c-interview-questions-answers1.htm Unlike above two web sites this web site is not having so many questions but it has only one answer of a question.Again please don't get confused,this is also a reference site for you.



Please make sure you have done step no.1 (compulsory for every one whether you are financially strong or not), step no. 2 or step no.3 depending upon your financial condition.

After completing these steps just make sure yo have done following very inportant c and c++ questions:(Sometimes these questions are asked during final HR round also)
