I was 30 minutes into the interview early because i want to be ready. My interview was scheduled at 4pm for Pfizer Singapore via webex online. After a wait of 7minute at 4.07pm, i realized that they are running late and how unprofessional they are at treating their candidate. If these is the kind of standards that Pfizer Singapore is upholding towards their candidates, i cannot imagine the employees working in there. HR called after 11minutes which is about 4.11pm and asked where am i, i told her i left after they were late into the interview. No sorry, no apologies or recovery in being late instead the HR gave a tone of displeasure and displeased when i said i did not want to proceed with the interview further. Big company does not mean you can start acting unprofessional.
