Honeywell Software Developer interview questions

1st round was a hacker earth round with programmings ques, i don't exactly remember questions. there was no reply from that round for around 2 months. Suddenly i was called for a interview process 2 days before in Bangalore office, for a weekend hackathon. It was a group collaborative hackathon event. they formed groups of 4 randomly, there were 3 problem statement mentioned below out of which we had to choose 1 statement, design and divide clear tasks within group. There were no instruction on language/expected output/ framework. they just wanted the result and code. No consideration of domain/language/experience/role you come from, it was same for everyone. I didn't stay till end of event that day, since none of my team mates including me had worked on this domain.

The interview process was really fast. Two interview, one behavioral/technical and the other with human resources. The first one was with two people asking question. The other one was with only one women.
