Getting an interview took me almost a month, and lots of questions are asked regarding GNSS. It includes not only some technical question but also behavior questions. They asked me a question to think more deeply.

First round was with HR manager, doing some basic screening on techinal background, checking if candidate generally fits the role. Second round was online programming/multiple choice questions on third party website. FInall round was with the team's Senior Engineers, where they dig deeper into techinical experience and some behavioral questions.
