*Round 1* : Apti round, basic apti questions were asked, I don't remember the exact topics but I can assure you, that you will be able to do it if you have basic idea of maths and how things work, which is first requirement for being an engineer so I guess you will be able to do this one. I don't remember if there was any negative marking but the point is quantity and accuracy of your answers both are important here.
*Round 2* : Training round, we were taught Core Java along with spring and Python(Flask), and the we had to make a project based on our training and topic assigned to us, In my case we had to make a website using flask along with Okta integration for authentication ( which was the real challenge here), In this round we had to follow complete Agile path for software development, in wich we had to write the Design docs(boring task) to basic wireframes and then the actual product.
*Round 3* : Interview/ Presentation round, this round was full of cross questions regarding our project to role of each member of team in building project, in some cases we were also asked Puzzles, GFG interview puzzle to be specific.
*Round 4* : HR round, this was a good one, I guess was best HR round I have given till now, coz there were lot of tricky questions and one of fav HR had on her plate was calling two friends together and asking them we are gonna select one of you, so which one should I hire and why. also one good question I remember was, what is worst thing you ever did in college that you regret doing.
