There will be 2 rounds interview, with basic knowledges about power electronics, such as BJT, op-amps, MOSFET. I got declined at the first round. The interview is enjoyable, makes no pressure for me.

Interview was very straightforward. A couple minutes expanding on details about your resume (projects, knowledge, experience using certain software tools, etc). Bulk of the interview was a circuits technical question, going into transistors, op amps, microelectronics, etc.
