Job interview at 27 weeks

Need some advice from anyone who’s been in the same position!

I’ve been wanting to work throughout my pregnancy with no luck, and I’ve been offered an interview this week. It’s mostly remote (only 8-12 days in office) and the interview is online.

I know I won’t be entitled to maternity pay. But, at what point do I disclose the pregnancy (I am showing but obviously can hide it during the interview process). This isn’t a dream job by any means, but with the current financial climate I’ll take anything at this point. Also how does maternity leave work if it’s a fixed contract and I’d have to leave around 3 months time to have the baby?

Any advice would be seriously appreciated!
