GLOBAL LOGIC(INDUS LOGIC)
COMPANY PROFILE
Founded in 1998, Induslogic is a leading software development services provider headquartered in the Northern Virginia area with a development center in New Delhi, India. In contrast to many companies in the same sector, Induslogic is the first US company with a wholly owned subsidiary in India. The company was founded to address growing enterprise software businesses' needs to reduce the time and expense required to develop and maintain software solutions. The primary differentiators of Induslogic are - an exclusive focus on commercial grade enterprise software, an unmatched quality of engineers (almost exclusively recruiting Indian Institute of Technology graduates), the use of industry standard tools and methodology, and a complete guarantee on work
PAPER
Question 1. What is the output of the following code when compiled and run? Select two correct answers.
public class Question01 {
public static void main(String[] args){
int y=0; //line 1
int x=z=1; //line 2
System.out.println(y+","+x+","+z); //line 3
}
}
A. Prints 0,1,1
B. Error during compilation at line 1
C. Prints 0,0,1
D. Error during compilation at line 3
E. Error during compilation at line 2
Question 2. Select three correct statements.
The garbage collection thread cannot outlive the last user thread.
The garbage collection can be forced by invoking System.gc().
The garbage collection thread is a non-deamon thread.
The finalize() method is invoked at most once by the JVM for any given object.
The finalize() method may resurrect the object upon which it has been invoked.
Question 3. What is the output of the following code when compiled and run? Select one correct answer.
import java.io.*;
public class Question05 {
public static void main(String[] args) {
Question05Sub myref = new Question05Sub();
try{
myref.test();
}catch(IOException ioe){}
}
void test() throws IOException{
System.out.println("In Question05");
throw new IOException();
}
}
class Question05Sub extends Question05 {
void test()throws IOException {
System.out.println("In Question05Sub");
}
}

Tech . Interview
My interview was held at 8.:30 of night .there were two person in interview panel. it was approx 45 min. along .
They asked me that wat ‘s my favourite subject ,
As my area of interest is programming , I told him programming in c-language , concepts of data structure and concepts of oops, I convincingly said that sir I m vry comfort with programming.. they asked me algo. of merge sort.. really friend this was the topic which I left because I find it little bit crucial but I made algo which resemble program by my own logic .
I said them that sir I m unable to write standard algo. but I implement the merge sort concept by my own logic, I convenced my whole algo and they impressed by it .
Further they asked abt. avl tree and their rotation ,they give a problem relate to rotation of avl tree and said to peform appropriate rotation to get height balance tree.
Further they asked about binary search and give me array to apply binary search.f
Frther asked that wat scanf function return.
I really forget that I said them sir I forget . they asked is it true, I said yes sir scanf function return something but I m not recalling , in addiotion I said about print function and their return value.
At last they asked a puzzle and I successfully solved it the puzzle is:- there is three basket , one hold apple , other hold orange and third one hold apple orange both. we don’t know in which basket wat is , basket are wrongly labeled means wat is label of basket , basket doesn’t fall in that situation. we are allowed to pick only one fruit from each basket and judge that wat fruit basket hold.
really friends this was vry interactive session. inetialy I was nervous but later I respond vry freely. sometimes I felt that this was not technical interview , this is technical discussion to that person, they are vry friendly. at last they asked u have any question. I asked :-
1. Sir,there is any need to learn and to know abt the company before joining company
they said: we have three month training prog. so u think u have any need to learn
I said:no sir
2) wat is my professional growth in ur company.
3) in which field I have to improve.
HR interview
this was tahen by hr mam and it was abt 15 min. long. she asked me abt my educational background , family background, my strength and weakness,careee objective.
further she asked :honestly said if u r not this field thn in field u might.
I replied: I were a traveler
she asked: why?
I replied: I want to travel whole world , I want to understand the people, their thinking , their behaviour, their culture.
she asked: If u r not selected then wat u will do?
I gave a little smile and replied: no problem mam, I work out on my weakness and try to remove them.
she asked: upto u who is a deservable candidate for my company.
I asked: mam included me or except me.
she said: except u.
I picke name of my batch mate who was also appearing in the interview.
she asked: why?
I explained lots of skils of them. it is so niece for me that he is also selected .
Little bit question on my exta curricular activities and hobby.
so friend prepare abt ur technical knowledge , they were seeking only a technical and logical brain person while they were less emphasizing on communication.
At 11:30 of night result was declared and I was among the selected candidate.

ATRENTA
atrenta - open to coe and ece - cutoff %age = 75% (came down to 74) for both branches
three sections in the paper - all 3 to be done (10 or 15 ques in each i thnk) - but 2 of these are weighted more
so if ur coe - 1st and 3rd sections = double weightage and 2nd = normal
if ur in ece - 2nd and 3rd sec = double and 1st = normal
first - coe based stuff - programming, error detection, output, algo - general stuff - nothing deep
second - ece based stuff - all the bloody OPAMPS and transistors (usually coe guys hate this stuff)
third - analytics - CAT based maths - reasonong and puzzle and math problem solving
atrenta gives very high weightage internally to this 3rd section - they are looking for minds with reasoning and analytical approach to problem solving - so if u crack the 3rd section completely (which is quite easy to do from a normal guys point of view with 75%), and score well in the respective category (as in either coe or ece), u have a high chance of getting thru

Paper Pattern
1. Online aptitude test.
that is u have to giv ur exam on a PC..
2. GD
Here they look for gud points..that is ur ideas are important n not how loud or aggressive u
are.
3. Interview
a few HR Ques are as follows..
- tell me smthg abt urself
- how do u look at life
- can u handle stress
- what is problem with working in teams
- No tech quesns were asked.But better be prepared!!!
