Solicité el puesto a través de la recomendación de un empleado. El proceso duró 4 semanas. Acudí a una entrevista en WD (Milpitas, CA) en feb 2017
Entrevista
I was first interviewed by hiring manager via phone for about 30 minuets. The interview was mostly simple question about my background and different skills listed in my resume. In couple of days I received an email inviting me for a onsite interview. The onsite interview took from 11 AM to 3:00 PM including lunch. Most people were nice and the questions included simple background questions. I was also questioned about the basics of 3D nand memory, how it works, writing and reading cycles and etc. I was able to answer almost all of the questions. However the hiring manager asked me some in depth questions regarding to Reactive ion etching of silicon for high aspect ratio structure which I failed. The interview also included behavioral questions. I did not receive any feedback from the company in a month. So I decided to call and found out they are considering other candidates.
