Anonymous Content Software Associate interview questions

I applied through elitmus. I interviewed at attra bengaluru in February 2018. Interview: 1st round: I got selected through elitmus. 2nd round: GD (My topic was Indian cinema). If you talk few lines is enough. Some of them who spoke 4-5 lines got selected. They won't reject much people in this round. It just for formality that you have to speak something. 3rd round: TR1 . They just ask questions from your resume. They won't go for depth. Just few lines for the questions they have asked is sufficient. And they check only your communication skills in this round and be confident. Interviewer asked me about my project architectural diagram and few questions on my project. They also ask some basic SQL queries to write. And HR questions will also be asked in this round like why attra? why u have taken engineering etc.. 3rd round: TR2. This round was bit difficult. Bcz the interviewer who i got asked me totally different questions compared to others. I don't remember all the questions asked in this round. Some of the questions like draw the technical architecture of how an eCommerce website works. Test cases for flipcart app, How it works exactly? What is client server architecture? And OOPS questions like using inheritance, polymorphism write a c++ or java pgm to demonstrate how flipcart app works etc. I got rejected on this round.
