(Higher weight than the remaining) in 8 balls with weight mechine?
Answer : 2 iterations
13.
2. Round - II:
-> They asked to write a C program and Essay (General Topic).
-> Essay is having very less priority so no need to worry about it.
1. Eleminate comments in c:
Program:
#include <stdio.h>
void main (void)
{
FILE *ip, * op;
chat ch;
int flag = 1;
ip = fopen("Source.c","r");
op = fopen ("Output.txt","w");
if (ip == NULL)
{
printf ("Source.c file not found!");
exit(0);
}
while ((ch == fgetc(ip)) != EOP)
{
if (ch == '/' && fgetc(op) == '*')
flag = 0;
if (ch == '*' && fgetc(op) == '/')
flag = 1;
if (flag == 1)
fprintf (op,"%c",ch);
}
}
2. Convert non intended lines program to intended lines:
Example:
Non Intended line program:
if(con)
{
stmt
}
Intended line program:
if(con)
{
stmt
}
Program:
#include <stdio.h>
void main (void)
{
FILE *ip, * op;
chat ch;
ip = fopen("Source.c","r");
op = fopen ("Output.txt","w");
if (ip == NULL)
{
printf ("Source.c file not found!");
exit(0);
}
while ((ch == fgetc(ip)) != EOP)
{
fprintf (op,"%c",ch);
if (ch == '{')
fprintf (op,"\n\t");
}
fclose (fp);
fclose (op);
}
-> These two are the most prequently asked programs.
-> And you can expect other programs also so concentrate on "FILES"
Concept.
3. Technical Round - I:
-> This is very important concentrate on body language also.
-> In this they asked completly on basics of Data Structures, DBMS,
operating System, and few questions on Apittude.
-> They may ask to explain "YOUR ACEDAMIC PROJECT".
-> They may ask to write programs and explain the logic.
4. Technical Round - II:
-> This is much crutial round.
-> They ask very complicated topic like "Complex Queries in DBMS,
Linked List programs, and Appitude also".
-> They conducted this round nearly one and half hour to me.
-> They may ask you to explain the program which you written in the
Second Round.
-> They may ask your Programming fassion.
5. HR round:
-> HR interview may take very less time (2 min) or long time (20 min)
that is dependent on your previous rounds performance.
-> If u answered all the question in the previous round correctly HR
will not ask much more quesitons,
-> In this round only you have to give your resume.
-> Deffinitely HR will ask atleast one question on your resume
(Prepare well to explain your Objective which you wrote in re your resume).
-> Most frequently asked question is "Why you got very less percentage
in B.Tech compare with Inter and 10th". Go to HR interview with your own
answer.
About Persistent:
-> Established in 1990
-> Having dealing with MICROSOFT, IBM, etc.
-> It is product based company.
-> Founder of Persistent : Anand Desh Pnade.
-> Persistent Head office is in Pune.
-> It is having multiple branches in Pune and also in Nagpur, Goa,
Bangalour, newly in Hydrabad also.
My Personal Opinion of Persistent:
-> It is very nice company for freshers.
-> You can get more knowledge.
-> You can easily get a job in some other companies, but it is
difficult to get job in Persistent.
-> The interview procedure is almost equal to the interview procedure
of GOOGLE, YAHOO. . .
-> And in other side pay package is very high now (3 lakh per year).
