Dear friends . . .

I have faced totally 5 rounds!

3. Technical Interview Round-I(Face to face Interview).
4. Technical Interview Round-II (Face to face Interview).
5. And finally HR Interview.

Development Life Cycle and little bit of apittude!

(Higher weight than the remaining) in 8 balls with weight mechine?

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).
