Microchip Technology Engineering interview questions

Initially got an email, set a date and time for a phone interview. The interview was completely technical. Asked basic questions about transistors, difference between NMOS and PMOS, asked about SMPS, Filters, digital logic etc. The overall experience was good. The questions were really basic. If prepared you would easily clear the round. The interviewer was friendly. Was my first interview. I guess I screwed up big time. Anyway, you prepare all your basics properly and you will have a chance!
