I applied this job on their website, and got the phone interview invitation two weeks later. The HR let me choose the date that I'm available, and set up the interview and reply to me quickly. The interviewer is an senior engineer, she wanted me to explain one of the project I mention in my resume, and ask me some implementation detail. And then she wanted me to talk about my understanding about CDMA. I think i was doing ok so far. And then she asked me what programming language I am good at. I'm good at C only, but her team prefer someone is proficient in higher level language. Later she explained what her team is working to me, and what she is responsible in the team. Finally she asked me the software development cycle, which I wasn't able to answer correctly.
