Safran Co-Op interview questions

2 rounds, interviewed for their Irvina, CA facility. One call with the recruiter and one with the hiring manager. First, I had my interview scheduled, and then 3 hours before it, the recruiter said that there was a conflict and we had to reschedule. I was then sent an invitation for the rescheduled interview for the wrong date, which I had to follow up twice to change to the right date. One month later, I got an email telling me that the hiring manager wanted to interview me. The day after the interview, I received a rejection letter in FRENCH when I was interviewing for a position in the US. I've never felt this disrespected by a process.
