Qualcomm Verification Engineer interview questions

I had applied on line for the post in October and got a call by the end of October. But it was strange because they never informed me of the phone interview in advance . He asked me what i was doing now and i explained what i'm working on and when i will be graduating. He then asked me about all the project that i had done.Then concentrated on the vlsi project that i had done .Even though i haven't taken any verification courses , i had worked on test benches for my project ,so explained that. He was satisfied with my explanation and told me i can come for an on site interview. In the on site interview , i had 3 technical rounds each of 30 min, concentrating mainly on the different projects that i have done , plus few basic qs from digital and analog design .But the questions were very direct and simple and mostly related to verification. I got the results of the interview after a week.
