Straight forward chat about experience and the firm, relaxed, quite quick too, less than half an hour. Only one stage. No tasks or further interviews. Had the offer a week later.

Applied on the 13th of October and got back to me a week later inviting me for the interview. Had to complete a short test before the interview. The interviewers were over 10 mins late which was not a good way to start. They never got back to me after the interview which was very unprofessional for a firm like this.
