KPMG Data Scientist interview questions

Four and a half or maybe five hour interview with almost every person on the team. They also required applicants to deliver a presentation on some topic related to data science. Though they ask that the presentation be non-technical, they hammer you with difficult questions on the spot and even ask you to write out the answer. For the interview itself, they ask you what you have studied and then proceed to test you on things that you haven't studied. One of the interviewers was extremely rude and didn't even look at me while she asked questions (she was on her phone scrolling through her Twitter). According to the team, the work-life balance is also awful. After the interview, no one contacted me, not even to tell me I didn't get the job. This was despite emailing about 7 people on the team, twice each.
