iViZ Associate Software Engineer interview questions

It was an off campus call. There were around 30 candidates in my batch. First round was a multiple choice Q&A inclusive of quant, programming and problem solving. Around 10/60 made it to Second Round that was On hands JAVA programming round with just two problems, one being extremely easy and the other one significantly tough(Interviewers keep cheking in between and there was no time restriction for candidates who were trying their best). It took me 3 hours to solve the second problem being the the only one one to solve that. After verification by the interviewer, CTO came in provide inputs and asked me to reduce the complexity. Another 20 minutes and I was done with the program. 4/10 from second round made it to 3rd round (F2F Technical with CTO and Project Manager). It went good and I answered almost all the questions asked, those which I could not answer I prefer not giving a fake try. Total 2/30 made it to 4th and final HR round.
