It was nice and good number of questions was asked and those are not that much difficult. Can answer them when we prepare good enough for an interview. It was a great expirence from them.

Recruiter forgot about interview and when interview took place they simply asked if I knew the used language and said they would set up the technical assessment. Have yet to receive confirmation of the time for the assessment.

The interview started with introduction of company's products and possible work opportunities. After that we moved onto my skills and expectations. And lastly there was a very simple test in C and C++ and some general concepts of baremetal programming.
