Boston Scientific Process Engineer II interview questions

after 10 days of applying they invited me for first interview. it was technical interview around my cv. there were 2 enginners for interviewing panel. they explained about their products and their back ground initially in a friendly atmosphere

I had a great interview, but never heard back even after emailing and calling multiple times 2+ weeks after phone interview. This is my biggest pet peeve and a large problem with interviewing (especially big companies). I hope you have better luck than me.
