Questions were rather technical and pretty repetitive even though I had already answered it previously. Manager wasn't friendly at all, and gave off that sort of uncomfortable vibe. Moreover, she asked a question about how comfortable I am to work after hours due to comms with global teams etc and she mentioned that she is asking this because "in Singapore, people are very picky about this and they are not exactly comfortable with working and responding after hours". That was the moment where I'm like, no thank you. There was never a rejection email either.
