These days I'm graduating from university with a bachelor's degree in electric engineering.
I'm currently preparing for job interviews in the HW / SW field.
I'd be happy to have a partner in this so we could "sit" on interview questions together.
People can't do your interview for you. My advice would be to research thoroughly the particular fields/technologies/products of any potential employer and based on that research think of likely topics you might be questioned on. You may also be asked to demonstrate original thinking, e.g. by discussing ideas of your own which could contribute to your potential employer's success.
