Interview preparation tips for other job seekers - Good place to start for freshers

Round: Test
Experience: They gave 4 sections..1)General apti 2)Technical apti 3)One prog 4)One algorithm..
1)General apti is little tough..he asked questions based intermediate maths..about circles,polynomials etc..u can
use trial n error method to solve them.
2)Technical apti he asked questions based on c programming and aome on theory..it is also multile choice type..
3)He asked us to write a program to delete comments in c..
4)He asked us to write an algorithm for next N pandigits in increasing order..where pan digit contain contains all the
digits from 0-9 only once..ex-5342981706
Duration: 30 minutes

Round: Technical Interview
Experience: There is only one interview including both technical and HR..all of them were asking questions.. first they asked me to tell me about myself..then they asked me to explain solutions for the program and algorithm given in the apti..then they asked me about my projects and asked me explain them..they asked me my favorite subject and asked questions based on that subject..they asked me some logical questions and some DS programming like write a recursive function for palindrome..total interview is about 30-45 min..it is very simple and easy questions only

Round: Test
Experience: The question paper consisted of 4 sections
1.Apti (Objective):this basically consisted of all math questions which covered topics like areas,limits,trigonometry..
2.tech apti (Objective ):this consisted of c questions only..
3.Problem solving:(Subjective) we were asked to write an algorithm to generate pandigital numbers.
4.Programming : 2 questions
1.code in c to remove comments from a c input file .
2.java code to print given M * N matrix in Spiral order .
There's choice in this section
Duration: 25 minutes

Round: Technical Interview
Experience: My interview lasted for about 40 minutes..they asked many questions on my summer internship and on final year
project.I was asked to write a c code to print a string in reverse order without using extra space.c code to find the sum of 2 numbers that is digit wise and to store the carry..that is how the addition is done manually by humans.,then I was asked to solve few puzzles..The entire selection process was good

General Tips: Be strong at coding and puzzle solving.and explain your final year project well..that is the kind of technologies you used in your project and the related stuff.So, all the best ..

Round: Test
Experience: In gen apti they asked questions on circle, probability etc. In technical there were three sections 1) Objective questions to find the output of simple c and c++ programs. 2) Write an algorithm to output next N PINDIGIT numbers of a given PINDIGIT number.3)Two questions of writting a program, i this we had to one only...One was
to print a N*M matrix in spiril(hellical) order and the 2nd was some file manupulation questions..Around 50 applicants were there in the apti.. They sortlisted 16 students. Out of which finally they selected 5 students. All the selected candidates were from CSE..
Duration: 20 minutes

Round: Technical Interview
Experience: In technical interview they asked c, c++, OS , DBMS, SQL, about Project.They asked.1)What are different types of joins.2)ACID properties 3)One to many relationship in sql.4)B+ trees 5)What is a process and how it is executed in os 6)How will you prevent deadlock 7) Some file system question from os 8)Puzzle-There are N coins out of which x are heads. A blind man has to divide these coins equally into two parts such that each side contain equal number of heads.9) Code of strcpy function 10) Database of Project 11) About the algo and code given in the written test.The key point in interview is leaving a legend at the end of your answer.Whenever any interviewer is asking any question if u don't know the answer clearly say i don't know but i know this this.. If u know,at the end just leave a legand so that interviewer will ask next question from that legend only.. Like in my interview he asked a question on process execution.. at the end i said sir there might a deadlock problem with the processes.. then he asked question from deadlock..

Round: HR Interview
Experience: No separate HR round was there. In technical interview itself one HR guy was there. But he did not ask any question.

General Tips: Prepare well C, C++, OS, SQL.. ALL THE BEST..
