Quantiphi Framework Engineer interview questions

I applied through campus 3 rounds in total. First is online test comprising of questions from quant,logical,technical(SQL,C/C++),etc.Test is of 90 mins approx. Second round is Technical inerview .... Third round is another interview (HR basically ) NOTE:I dont know why I was not selected as my both interviews were up to mark and as I had qualified for first round and second round was purely HR based and I had answered all questions there as well (even my english communication skill is better than the interviewer at second round).

The interview process consists of 4 rounds 1 round is onsite it consists of 8 sections time constraints are high Try solving maximum questions correctly 2 and 3 round is Technical All their technical round consists of 15 minutes so they don't ask much 4 round is HR They don't give a reply if you are not selected very bad interview process students have to interview even at 11 of midnight if after a round you didn't get a mail of congrutalions means you are not selected
