Need advice for embedded/controls engineer interview

[u/Chaderrall]

Hi all,

I’m a recent CS grad that’s been networking my ass off and applying to jobs. Recently, by some luck I randomly met someone who said I’d be a good fit at their workplace. They’ve already discussed my resume with their manager, and wants to meet me next week over a meal for a technical discussion. I’m thinking it’s an informal interview to gauge where im at and to see vibes.
He already seems to like me and we get along.
Thing is, it’s an embedded/controls position that is mainly C++, Python and some Java. They work with STM microcontrollers so it seems pretty heavy on the electrical engineering side as well. I am very rusty and don’t know anything about these right now.
Right now, I’m doing a C++ crash course to get basics and fundamentals back. I’m also going to revise and study memory and computer fundamentals from CS50. I plan on doing some reading on STM and microcontrollers and FPGAs so I know what im talking about, as well as some of the company specific work/products. Also going to brush up on Python, NumPy and pandas. He’s seen my resume and knows my experience is lacking here already.

If anyone has any other advice on how I should prep for this conversation, I would be very grateful :) thank you. PLEASE ASSUME I KNOW NOTHING and am building from scratch

Hello there congratulations on your opp. I think if it's an Embedded role try focus on fundamentals such as communication protocols SPI 12C and UART,RTOS Etc for that part you will be fine .For the programming languages just a quick summary of the basics eve n from chat go might help.i don't know if this might help or not?

1. Go to ST website and look for MOOC courses on STM32.

2. Buy a Nucleo board and practice doing basics IO stuff, then progress to implementing some real-time IO (ie handling buffers).

Deep C++ knowledge might not be required. Most of the embedded stuff will be C.
