Overall very through, with final onsite interview lasting around 4 hours that included a written case and quant problems. It was quite tiresome because the interviews were back to back.

Maths and Verbal reasoning tests online (relatively standard). Interview with 2 consultants from the team I was applying to. Standard competencies interview, though with some coding-specific curve-balls thrown in. Major complaint is the ludicrous behaviour of the (previously very communicative) FTI following the interview. In almost 2 months since the interview I have had zero communication; I am left presuming a rejection that they don't even have the decency to send me. Shocking approach to hiring experienced candidates from a large company.
