I went through 2 interviews that were really easy. The first was a phone interview, I was asked a few basic electrical questions such as ohms law. The second was on onsite interview, that was much the same, but I was also asked to interpret some simple line graphs. There was also the typical line by line questioning of my resume, and in addition to that there were also some personality questions. It was a really easy interview and not stressful or intimidating at all.
