Cisco

People at Cisco are very friendly, which puts you at ease even during interviews. They do not require a formal dress code; just ensure your attire isn't too extravagant.

I had one online interview and then a face-to-face interview. Both were pretty simple with basic questions. I had to explain myself and my skills, including basic knowledge of analog and digital electronics and PCB design.

I had a technical interview with Cisco through the use of a Google spreadsheet. I was interviewed by two engineers. The interview took about one and a half hours. They were very nice and made me feel comfortable.
