Upcoming DSA round for SDE-1 at Abnormal AI

I have an upcoming DSA interview for an SDE-1 role at Abnormal Security (Abnormal AI).

If anyone has interviewed there recently, could you share what kind of DSA questions were asked, the difficulty level, or specific topics/data structures that are worth focusing on?

Any insights on the interview format, common patterns, or preparation tips would be greatly appreciated. Thanks!
