PCCW Senior Java Developer interview questions

From interviewer to HR all are unprofessional. They do not have courtesy to respond to candidate's enquiry. I went through interview process and interview lasted for 2 hrs. After the interview, interviewer told that, he is happy with my interview and it's positive. And I will hear from the HR regarding the next steps. Its been almost a month and there are no words from the HR. Very disappointed feels like wasted plenty of time for nothing . A big NO to this company, as they lack basic etiquette in corporate world. This company must have very poor infra. I would never recommend anyone to join this company. Join only if this is the last resort.
