3rd round– it was again a technical interview.the interviewer started with basics of java like collection(hashmap,set),OOPs,what is jvm and jdk,again comparison between c++ and java,oops in c++ vs oops in java i told him that i prefer c++ for coding and java for OOPs concepts.in the last he asked “do you have any question for us” and I asked.

HOW TO CRACK EPSILON INTERVIEW??

Start with competitive coding as soon as possible, one can follow websites like geeksforgeeks, interviewbit, hackerrank, codechef. (I followed the first 3). Be healthy, be it placement session or the summer break before the placement session, make sure you pay attention to your health both mental and physical.

Most of the companies as for Aptitude and Reasoning in initial round, prepare for that as well but it won’t take that much time, you can follow indiabix, RS Aggarwal book for the same. Mock interviews are very important, form a group of 2 or 3(max) and help each other out, it will help you a lot, you can ask your seniors or placed peers for help regarding the same. Initial rounds are really important and mainly focus on competitive coding, aptitude and reasoning, make sure you make it to the interviews. Make sure you are familiar with every single line on your resume.

Projects are really important, before interviews, go through your project report or any sort of documentation that you have for your project and read about the latest updates in technologies that you used in your project. Get used to white board coding, most of the companies ask you to write code on paper during technical interviews.

Make sure you know everything that is mentioned on your resume. The Projects that you have mentioned on you resume are really important, make sure you have in depth knowledge about what your project does. Do check the latest updates in the technology that you used during your projects.
