The manager reached out to me from his database pool, as I had submitted a resume a couple of years earlier. I had five on-site interviews. They did not seem to have a standardized set of questions to ask. This felt unprofessional. I was surprised at the low level of difficulty of questions they asked a candidate who had flown in from out of state, spending an entire day at their facility. Perhaps this was because the skill set I was hired for was not their core skill.
