Interview Preparation Tips
Experience: The test was conducted online. All the questions were of medium standard and easy to crack if we have patience for thinking.
English comprehension level is slightly below the standard of CAT. Those who have the habit of reading English news paper can easily crack the test.
Data analysis questions were also of medium standard. Those who have knowledge about graphs, bar & pie charts can easily crack the exam.
Tips: Practice Aptitude questions from R S Agarwaal book and CAT material.
Round: Technical Interview
Experience: Over all interview experience is cool. Interviewers never grilled on anything. In many cases they have helped me to arrive at answers.
Tips: Read C++ and Oops concepts from E Balaguruswamy text book.
For Data structures and algorithms read 'Data structures' by Yeshwant kanethkar.
Minimum knowledge about all the courses of your department will be an added advantage. This will help you to depict you are sincere in your studies and don't have any personal constraints in learning a new thing.
General Tips: Just be confident and believe in yourself. You will get through.
Skills: Programming skill in C++

Interview Preparation Tips
Experience: The questions were tricky. We were given a paragraph and after reading it, a statement was given to us and we were asked to say if it is true, false or cannot say. The structure of the statement put us into a a tough place. So practice of such kind of questions is necessary.
For data interpretation questions a good hand on basic statistical mathematics is needed. One has to be quick because of the time crunch. The questions were approachable
Round: Technical Interview
Experience: In this round my resume was scanned and I was required to speak about myself, my projects and explain certain areas of my resume. The interviewer picked up one of my basic project, surprisingly, and asked me to elaborate on it. He asked me how I can improve the project. And I had to write a code to make that change. Basically, one should have a good idea about the projects they've done/ mentioned in their resume. And know it in detail.
Few questions on data structures. Prepare well for coding type questions and data structures.
Round: Puzzle Interview
Experience: The interviewer asked me two puzzles. They were moderate level. And also luckily he was helpful whenever I got stuck.
Round: HR Interview
Experience: HR round was good. Basic questions like " tell me more about yourself", brief information about my past history, college life, extra curricular activities. In the end she asked me, "should we hire you?" And I lightly answered " why not!" So it was a good interview overall.
Skills: Coding Skills, Team Working Ability, Project management
