R3 was technical interview round , so my interview took 45-50 minutes but it's totally depends on interviewer and your knowledge , they will ask you basics of programming fundamentals and what you have learned in college and how many projects you have made during your academics , in my case interviewer asked to me some aptitude questions from number series , and ratios , so you have to prepare for some aptitude and reasoning also . There will be some tricky programming questions also . Interviewer checked my coding skill and checked that you are aware of syntax of java and classes or not , so he asked me to open my vs code and said that "please make a class and create an object " So I did it successfully, then he asked some array questions like searching sorting , max ,min . I did it . After he showed me a code and said please write it's output. So I gave him correct output , but he was very supportive and calm , my overall experience was good , at the end he asked me "you have any questions?" So I said yes ,, I asked him that "why it's roles are like genc genc-elevate etc .. what does it mean" (you want answer of this question you have to ask in interview , I will not tell you haha) . Show them that you are interested for the job interested for the company ,so ask some questions at the end and make some good impressions .
