any advice/suggestions to intensively brush up on modern C++ and multithreading for an interview that will likely be technical and cover bases like algorithms, data structures, etc?

I haven’t done c++ for awhile since a few courses in college - I did parallel programming and GPGPU on the side, but nothing on a professional level.

I’ve been mostly doing front web dev since I got out of school and C#, so I’ve been more on design/higher level of abstraction in dev and if I am asked things about pointers, memory allocations, etc I would probably draw a blank but I am motivated to no life it hard for the next week to catch up again.
