I applied online. I interviewed at Boston Consulting Group (Singapur) in Jan 2026
Interview
Very bad experience. The HR staff in Singapore is the worst person I have ever seen.
After I received the first email about the notice of the online coding test, I got cold and fever, so I wrote an email to request to delay the online coding test, after about two weeks (too long), I got reply and the online coding test is rescheduled.
After I completed the online test, I was shortlisted to HR interview round. I have to say this HR staff (a woman) is the worst person I ever met. She just ask one question and the duration is only a few minutes.
I cannot believe that BCG has employed so bad HR person which is not professional and not polite in some sense.
