I was interviewed when I apply as a technical audit at Astro, there was 4 interviewers interviewing me for 4 consecutive months including the HR session whereby I communicate my employment expectation. After I finished my bar raiser interview, they asked me for a payslip and reference numbers (coworkers, superiors and HR) which I believe when I decided to give my personal and confidential information they will proceed me for offering. However, they disappear for 1 months after I gave them them such information. I think it was unprofessional to ask such personal and confidential information when the company still unsure to hired someone or not. They even contact my ex-superiors, HR and Coworkers to ask like 10-15 long questions which also waste their precious time.
