Panel Interview with 3 people. One Supervisor and Two Lead Tech's. I felt from the minute I walked in I was treated with high respect. Felt comfortable within minutes of sitting down. REMEMBER: to bring your Passport or Birth Certificate. It is Required for a tour. If they are interested in you, and you don't have your Passport or Birth Certificate, you will be invited to return for the tour. The interview process will take approx. 45 minutes to an hour. Be prepared to answer some RF questions that are not easy. The Ohm's Law questions are super easy. First day Electronic school voltage divider, voltage drop and current questions in a series circuit.
