Qualcomm interview questions

> When does a metal become a transmission line; answer is t rise > 6 Tdelay > given values of transmission line impedance, driver impedance and load impedance was asked to calculate reflection co-efficients at source and load, transmission co-efficient > what happens if source/ load impedances are not matched with transmission line impedance > how to reduce ringing > explain cross talk with a given scenario and ways to reduce it; both due to inductance and cap > ground bounce; how will you reduce it > inverter sizing; why do we size in that fashion > verilog behavioral and non-behavioral and what is the hw implemented in each case > implement a counter counting upto 10 in verilog > from resume; explain about the PLL that you have designed

No doubt it is difficult to land a position at QC. We would get hundreds of resumes a day, so you really have to stand out. Specifically tailor your resume' to the job description you're going for, if you can. HR will hit you with a feeler phone interview, then one of our senior staff will follow up. Depending on the person you get, this could be easy or very difficult. Know the basics of sw engineering and systems. Know the types of memory SW uses & OS fundamentals. Be prepared to answer a programming question on the phone. If you get past that, they'll fly you in and you'll interview one-on-one w/ about 6 people who will grill you (I was one of them). Answer questions to the best of your ability, but don't get too cocky. If you get stuck, ask them what they think of your idea. Have a positive attitude, be friendly, and relax.
