It took about 3 months, and HR called me for the first interview and then the operational and the lead called me, once completed I flew out to California for the final interview. Once they're they asked me a few questions about my experience and how my work life is. After that, they showed me around the area to see where and what exactly I would be working on. After the interview was completed I felt it went pretty well but I didn't get the position. I really don't know what they are looking for maybe someone with less experience so that they can mold them to what they want
