Technicolor Workflow Developer interview questions

The first round was aptitude round basic aptitude questions. The second round was technical round basic oops concept questions were asked and some programs. The third round was manager round it was not an interview per say it was just an interaction with the manager he asked basic hr questions. After a day I was told that I cleared the manager round and they scheduled my HR telephonic interview after an hour and it's been a month and I am still waiting for their HR interview call. They don't even pick up the phone and reply back. Worst experience ....
