Philips Software Technologist I interview questions

Questions were mostly related to design and architecture, the interviewer was visibly impressed with the answers and told that there would be another round with the manager the next day. I called the HR couple of times over the week but there was no response and finally, after a week I received that I wasn't selected!. This was such a shocker. I was in anticipation the whole week to attend the next round and this poor attitude from HR and interviewer reflect the level of professionalism. I didn't expect this from Philips!
