The process took 2 weeks. I interviewed at JPMorganChase (London, England) in Jun 2018
Interview
1st interview - technical (interviewed by a director. sound C++ questions covering C++11/14 and concepts
2nd interview - 1 hour (interviewed by a VP. interviewer asked absolute nonsense, like do you prefer a list or map? I asked him in which design context. His repose was in any context. I explained him mathematical complexity of each implementation. Then he said he always choose a vector over list because of memory page faults :) std list provides and custom allocator which can be customised to fixed block allocations. I doubt he know any C++
3rd interview - 1 hour, Team lead, complete techno functional stuff. Interviewer was cool and good questions
