Well what I'll say is this: my job never had leetcode. Embedded engineering, especially if you do FPGA work, is very different from what leetcode has. Honestly if recruiters are using it for jobs like mine, they really don't get it. But I don't know you nearly enough to know. There are so many different fields up and down the stack. Front end, backend, embedded, cloud, edge, consumer, IoT... The list goes on. I would cast a wider net, I guess.
