In my opinion, MNJ is deciding what they want on the fly as they meet interviewees. They told the recruiter that presented me they would not extend an offer because I didn't have an AWS certification for a collaboration consulting role (not sure why it's applicable), three days after communicating to the recruiter and me that an offer was on its way. This just left a bad taste in my mouth and I think I may have dodged a bullet not going to work at MNJ.
