Preparing for Embedded software and Firmware engineering roles at top companies.
I am planning to apply for similar roles at Microsoft, Apple, Amazon, Google...
I have been doing some LC (solved 120 with a good mix of medium and easy with some hard questions).
Along with this I want to brush up on rtos and basic embedded conceptual questions. I want to know if there is a book which I can refer to to brush up my concepts regarding the same.
I would also welcome any company specific suggestions which I should consider preparing before I start applying for such jobs.
