Philips Software Engineer I interview questions

One of the weirdest things happened.First, they conducted an aptitude only test but the day after all the students were called to retake the preliminary round.This time it was coding round.The coding round's name was automata.

First we had an online test containing Aptitude English Maths Technical After that 40 were shortlisted for the interview. Two interviews Technical and HR During the interview process I was one of the first one to go. The guy was sweet and nice. Almost everyone had both HR and technical, only 4-5 of us were made to wait for more than 6 hours after our technical round and didn't even get considered for HR even after waiting for so long.
