Aiyohhh, that sounds frustrating! Honestly, sometimes interviews go super fast like that, but don't assume it's because of your bump, lah. A few of my mum friends went through job interviews while pregnant and some got the roles anyway, so it's hard to say what the real reason was for the short time. Since you didn't get a chance to share much, maybe try sending them a polite follow-up email with a bit more about what you can bring to the team, at least then you've put your best foot forward, and if it's meant to be, it'll work out. Take care of yourself lah, you're 36 weeks, that's already a lot on your plate!
