Zeta Interactive:

Hi all, I am a student from VNR VIGNANA JYOTHI INSTITUTE OF ENGINEERING & TECHNOLOGY, Hyderabad. Zeta Interactive visited our college for a pool drive including MLRIT and GRIET on October 7th 2013. We had a written test, group discussion and coding test on the 7th and interviews on October 9th. The package offered was 2.4 LPA, with rotational shifts and a cab facility for night shifts (but they behaved like they are offering 5 LPA, wanted exceptional candidates with high scholarly abilities as is not the case with other companies with even higher packages and it was a frustrating experience). Only CSE/IT people were eligible. Upon request, they allowed ECE people also from our college (but selected none). The selection process is as follows,

Written test:

It was an online test with 60 questions and 60 minutes. Each question carries 1 mark and there was no negative marking. The first 30 questions were asked from quantitative aptitude and logical reasoning. Questions were asked from number system, time and distance, time and work, averages, percentages, simple and compound interest, permutations and combinations, probability, boats and streams, profit and loss, trains, ratio and proportion, problems based on ages, number series, seating arrangements, blood relations, coding and decoding. All the questions in this section are from the internet, all the questions were taken from previous placement papers of different companies.

The second 30 questions were related to computers (C, Java, OOPS concepts, OS, DBMS etc). All the questions in this section were from IndiaBix website; even the options were also exactly the same. So prepare the questions from IndiaBix. The cut-off in the written test was 27/60.

Group discussion:

Shortlisted candidates were divided into batches of 12 members and GD was conducted. The topic we got was, Is T20 a better form of cricket?

Some of other topics were:

-Facebook.
-Social media.
-Is marriage a necessary thing to maintain a relationship?
-Studying in one field and working in different fields. Is it the right thing?

We were given 2 minutes to think and 10 minutes to discuss (take a pen and a white sheet). After exactly 2 minutes try to initiate it yourself, don't let HR say 'start'. As time is only 10 minutes and there are 12 members you need to take your chances and voice your opinion confidently while listening to others. Listening and speaking is very important. Try to speak at least 2 times. On average 6-7 were selected from each group.

Coding test:

After GD there was a coding test. We were given two programs, one from SQL and one from C language, with a time of 40 minutes. They were:
¢ Write a C program to perform the multiplication of matrices.
¢ Write a code in SQL, to obtain the contents of 'n'th row in a table of data.
Some people got another C program. It was:
¢ Write a C program to perform addition and multiplication of complex numbers.

Interviews:

There were 3 rounds of interviews, Technical interview 1, Technical interview 2 and an HR round. If you can clear the technical rounds then you are done.

My interview questions were:

¢ You are comfortable with C or Java? (I told C and I know basic concepts of Java).
¢ What are the data types in C and what are their ranges? (told).
¢ Why the range is different for signed and unsigned data types, what is happening internally? (because the first bit is considered as sign bit for signed types, the range is different).
¢ What is a pointer?
¢ What is a union?
¢ What is a structure?
¢ What is the difference between malloc () and calloc () functions?
¢ What happens if the memory is already full and you use the above functions? (a null pointer is returned).
¢ What is the difference between a register and a volatile variable?
¢ Why registers are very fast?
¢ What will you do to solve the problem of 'memory leaks'?
¢ What is a static member in Java?
¢ What happens if I create an object and try to access a static member with that object?
¢ What is recursion?
¢ Have you come across the practical application of recursion? (I said finding factorial of a number).
¢ What is the need to go for recursion when you can do the same with a loop?
¢ What is a VOID pointer and what is a NULL pointer?
¢ Where do you use them?
¢ What is a deadlock?
¢ Write a C program to concatenate two strings using pointers. (wrote and explained).
¢ Write a C program to write a sentence to a file. (I said I am unable to recall the concept of files).

I lost in the first technical round. Definitely in one of the technical rounds they asked about the project. They are very particular about the academic project. Prepare a very good explanation of your project and all the possible questions from it. Questions related to DBMS, SQL and OS were also asked. Other questions from Java which were asked mostly were:

¢ Write a program in Java explaining static and dynamic binding.
¢ Program to explain all the operations on threads (multi threading).

They gave preference to people who were very good at Java and JSP. Offer letter was given immediately after interview if selected. There was a 2 years bond.
