The first interview was over the phone. I got a call after about 2-3 months when I submitted the application. We discussed general items from my resume.

A few days later, I received a call to set up a face-to-face interview for the following week. The interview lasted for about 7 hours, and I had an interview with 10 different people separately. They all asked general questions from my resume, but they each had 1 or 2 technical questions for me. The final interviewer was the HR Director, who asked general behavioral questions about previous work experiences/employees.

After about 3 weeks, the HR Director sent me an email notifying me that I was not the selected candidate.

Can a non-inverting op-amp have a gain smaller than 1? Why or why not?

If you have a "black box" circuit, and your options of what's inside is a constant voltage source (CVS) or a constant current source (CCS), what kind of tests can you do to determine what's in the box?

If you have an IC with a maximum temperature rating of 75C, a junction to ambient thermal resistance of 50C/Watt, and a power dissipation of 1W during normal operation, will the chip be able to function in room temperature?

If you're providing a product to a customer, for example a temperature sensor accurate to 1C, how do you know it's actually accurate?

How do you perform a continuity test on a chip?
