She’s kissed her impostor syndrome goodbye, and become the breakout talent of Industry – a drama so great that the Game of Thrones cast is queuing up to appear in it. She talks about fear, feminism and The Book of Mormon

On a video call from her New York apartment, Myha’la looks sufficiently ready for business in an all-black outfit, undersized glasses pushed down the bridge of her nose and the cityscape outside dominating the frame. It’s fitting: we’re here to discuss the return of Industry, the hit BBC/HBO series she stars in, which is set in a merciless London financial centre recreated in a Cardiff studio.

Over the past two seasons, we’ve delved into the deeply stressful environment of fictional investment company Pierpoint & Co, based on writers Mickey Down and Konrad Kay’s own experiences as overburdened finance grads. It’s a world where your colleagues are more likely to offer you a line of coke than a cup of tea, and where Myha’la’s character Harper Stern uses her talent for bending the truth with aplomb. But if you look just below the surface, you’ll find horrors of all kinds; in the opening episode of season one, one of Pierpoint’s overworked and undervalued graduates dies in the office toilets.
