TLDR: Random interview with random questions. The culture of the company seemed a bit off. I wouldn't recommend it even though the company seems like it has some potential. The interview was pretty easy but gave me a really negative impression of the company. As for the content of the interview, it was pretty normal. Regular embedded software questions. However, it was obvious that the interviewers didn't have any plan because they were asking random unconnected questions. There were two interviewers. One was a nice person who looked a little bit in a hurry even before the interview started. Maybe it is just my impression but he seemed like he had too much work to do and was all over the place. The other interviewer was not so good. He asked questions in a very weird way. He seemed like a good programmer without much experience but with too much ego. Some kind of personality to be avoided. If he behaves like this in an interview imagine on a day-to-day basis. The interaction with this engineer was an absolute no-go for me. Please take this feedback as constructive criticism. The company has the potential to attract talented people. I hope my review helps you.

The interviewer ask questions in depth until your knowledge is broke,I believe the interview is designed not to hire a normal software engineer with 5 year of experience but rather interviewer evaluate you if you have 10-15 years of experience for the mid level role,The interview process need to change in this company.
