I was recently rejected for a quant/dev role at an hft firm, ostensibly because my C++ wasn't up to snuff. I want to rectify this but am unsure how to go about it, as I'm very ignorant of the field and am having trouble finding transferable books and problems to work on.

I've had a couple of ideas of what might help:
- Getting a grip on concurrent C++. I've been reading the Anthony Williams book https://www.amazon.co.uk/C-Concurrency-Action-Practical-Multithreading/dp/1933988770.
Coding up some ML models in C++ might be good practise for concurrency (with potential GPU involvement)

- Coding an OS? Possibly far too ambitious but I imagine it'd be perfect for getting to know the low level lay of the land. I found an interesting book which attempts something fairly simple at https://www.cs.bham.ac.uk/~exr/lectures/opsys/10_11/lectures/os-dev.pdf.
There's Minix out there too for more gnarly challenges https://www.amazon.co.uk/Operating-Systems-Implementation-Prentice-Software/dp/0131429388

It seems like the OS/systems programming path might be the most appropriate. If anyone has any books/project suggestions which might help hone the necessary low latency/low level C++ craft then I'm all ears!

Did you try asking them for feedback? Sometimes they will actually give it, which will help you improve.

Concurrent C++ might be a good start.

Their feedback wasn't too specifc, just that my C++ let me down. I held off asking what flavours they were looking for in particular but will give it a go. Certainly concurrent C++ sounds like a necessary skill. Thanks for the suggestion

@ mrdivorce
It sounds like generic refusal. Try to get more info.
The real reason may be more mundane. Like the guys
didn't like your suit.
