The interview process was one of the most unprofessional experiences I have ever had interviewing for a role. I applied and was requested for an initial HR interview a week later and asked to give available time slots. I replied, and HR never got back to me so I followed up with them. Then I followed up with them again. Then a different person in HR contacted me and set up a call which was pretty unremarkable, if a bit dull. After this I heard nothing for about 2 and a half weeks. I sent an email to HR but they didn't get back to me. Then I got an email asking me to a second interview and asking when would suit. I replied, but they never set anything up or confirmed receiving my message. One month later I was sent the same email asking for a second stage interview. I responded but again, nothing was acknowledged or set up. I assumed the whole thing was a scam at this stage and forgot about it until 2.5 weeks later I get the same email from someone else in HR asking me to the same interview, with the same people. I sent the same availability response I always do and highlighted how often I had been invited and yet never actually interviewed by OpenClassrooms. Which is exactly what happened AGAIN.
