Honeywell Developer interview questions

I got call from HR and then interview scheduled as 2 rounds were there on same day. First round went good than got confirmation that shortlisted for 2nd round and than 2nd interview was comparatively more easier and I have answered all questions and 2nd round was also good. And in the end of 2nd round, interviewer told he will get back to me. I expected that I have been selected since 2nd round was also good and interviewer told he will get back to me. But didn't received any feedback even after weeks and finally I call hr and than hr said you were not shortlisted. What a waste of time it was, despite of good interview they rejected. If they have to consider some other factors while selecting than why taking interview and wasting candidates time Pathetic experience

Interview process took one week firstly they took the exam in that aptitude and some technical topics like c concepts and Linux concepts and Networking concepts covered then they took interview which was on vedio call
