JQ Investments interview questions

One technical 4 hour take home test. Then a zoom interview. Some brainteasers that are standard in the industry. Then some weird questions, for example the interviewer asked if my pc had graphics card. I guess they wanted to test technical knowledge, but in this context I found it odd and conveyed poorly.

First-round HR call for 30 min. The second round is C++ OA lasts for 4 hours, including 5 problems. Need to set up the coding environment yourself. The third round is an interview asking questions about mathematics and probability. 10 min Quick question and answer about programming language.
