Qualcomm Embbeded Software Engineer interview questions

First they introduce the company and the team then they ask me to introduce myself, and finally they asked me a few technical questions, and that's about it. it lasted about ninety mins.

Interview consisted of an hour long initial phone screen and then a "round robin" interview with many other candidates. Interviews were both almost completely technical.
