Preparing for Quant Trading Intern OA and Interview with DRW

Recently, I've been preparing for the Quant Trading Intern OA and interviews, and I feel that the style of questions varies a lot across companies.

So far, I've received the OA from DRW. Are there any question banks with similar problems?

dm me

you can dm me, i took it recently

quantguide has questions labeled by firm, some may be a little outdated though

有人能私信我这些问题吗

想问一下最近考过的同学，DRW 这个 OA 主要卡的是速度还是难度？除了 quantguide 按公司分类的那套题，实际做的时候更需要练心算和概率期望，还是也要准备逻辑推理这类题？如果方便，也想了解大概的限时和题量，谢谢。
