Infosys Software Developer interview questions

I was recruited by Infosys through a pool campus recruitment drive. I had an online aptitude round followed by two face to face interviews before being recruited. The aptitude test was conducted on the company's own platform. After the cutoff list was announced, those who made it had to face one/two rounds of interviews, the results of which were notified through Email.
