Squarepoint Capital Graduate Software Developer interview questions

Had my first round technical interview (1h), introductions (5min) -> C++ trivia (15min) -> leetcode (35min) -> QA [5min]. Stuff like l/r-val, virtual methods/tables, principle of 5, RAII, pointers, smart pointers and their use cases, etc.

Hackerrank OA - 1st Technical - 2nd Technical - 3rd Technical - HM - Offer. I got rejected after the 3rd technical but first 2 are trivia + leetcode, final one is a longer coding task. Less than a week in between every round and feedback within 2-3 working days.
