Interview Preparation Tips

Interview preparation tips for other job seekers - I am currently been recruited as a fresher, so my experience is based on my campus placement. So the process begins with a written test. The written test has general aptitude questions, Logical reasoning, Pseudo codes and hands on coding. The second round was a group discussion round wherein, I was grouped with 9-10 other members. Our topic was a bit on the easier side- Our lockdown experience. But the other batches were given quite debatable and controversial topics like whether sports and extra curricular activities be introduced in corporate industries? After this round we had technical round wherein I was tested on some basic skills like DBMS, OOPS and one programming language. The final round was the HR round. For me, this went for a little long. I was mainly asked my project and my part and contribution in it. Expect a few behavioral questions as well. Do not stress. Always remember to answer all behavioral questions in a polite and positive tone. And most importantly avoid using negative terms.
