Argos Multilingual Project Manager interview questions

They contacted me via LinkedIn. I sent my CV and answered the questions asked from HR. After that an interview was settled. The interview supposed to last 40 mins. However they were so friendly that we have talked so long and time passed by, it took 1 hours. I thought that they will contact me regarding the next step; however, they did not contact me since than neither positive or negative. I have asked my status via email and they never replied me back. I was ghosted for 2 months and I do not know why as my interview went smoothly.
