Well first contact was via email, and from the beginning you could tell it won't go well. The HR person with no prior contact just sent an email inviting me for a face to face on a given date, before cancelling and then sending another email asking whether I was available for a face to face, whereas I appreciate the speed of all of this, it was a bit strange as I could have been just a robot applying for it! First (and last) interview was with the hiring manager and another person, focused initially on my CV and experience and then moved on to scenario based interview and asking me a few mathematical questions along the way and asking me to draw things like the normal curve, log normal etc or describing a scenario and asking what the graph of the output will look like....it was quiet thorough and detailed. Unfortunately even after being told I would hear back, nothing came back even after sending a follow up email....I checked the recruitment system recently and the status to "Declined/Rejected" was only updated recently.
