Cboe Senior C++ Engineer interview questions

Around 6 interviews and a home task. The process was well organized and quick. The delay between stages was up to 1 week but mostly quicker. The interviews were reasonable and friendly. No strange questions. A lot of pretty smart questions showing profound level of the interviewers' expertise. The home task was of a reasonable size. I've almost finished the entire process but had to decline as got an offer from another company.
