I took my BCG Potential Test on July 2019 and passed. I was supposed to have my interview on August but I encountered several problems with my personal schedule, hence I had to reschedule to a later date on September. The HR in-charge said she didn't know the schedules yet so she couldn't give me a date and that we should just get intouch again when September comes (my last conversation with her). However, my work schedule got very hectic and I completely forgot about it so I didn't have time to continue my application till now. The HR person never followed up as well.
Would it still be possible to pick up my application where I left it and schedule my interviews next month? Or do deadlines exist on how long one can delay interviews?
