Don't waste your time. The interviewer turned up very late and asked irrelevant technical questions even though it was a competency interview. There was no assessment of problem solving ability in the questions,
It was clear the panel didn't read my CV beforehand and were making up questions on the spot.
After speaking with an insider, it's very clear the culture of the firm is very different to what you would get at a UK/US or European bank. The other reviews here echo this so I'm not surprised by the low 3.5 star rating here.
Before applying, try and reach out to connections you may have there who can give an honest opinion.
