Caterpillar Software Engineer interview questions

Four rounds for on campus: Online test in AMCAT portal Coding round in same portal Group Discussion Interview- Technical and then HR. I cleared all rounds till Technical but couldn't make it to the final HR round. The HRs who handled both the GD and interviews were so gentle throughout the process.

GD followed by interview on the same day. The topic of GD was day without mobile phone.A single interview with 1 person asking technicals and the other asking hr questions
