Texas Instruments Analog IC Design Engineer interview questions

Met the TI HR person at a job fair in Austin, TX, 2 business days after I was laid off from my job there. Scheduled for 2 days of interviews 1 week later, each day for a different position. The 1st day was for a power management IC designer working in a bipolar process. I thought this interview was very difficult. I interviewed with a TI Fellow, a Sr TI Fellow and Senior Member Tech Staff, and 2 others. A full day of challenging questions. The 2nd day was for a class D power amplifier designer, working in bicmos processes. Since I had a lot of background in audio in general, and class D in particular, I found this day of interviews to be very easy and enjoyable. Have never done so well in a job interview as I did on this day. Apparently, the 1st group's need was greater, because an offer was made for the 1st job, but not the 2nd.
