Allstate interview questions

Too Lengthy interview process - had 8 interviews for this senior role and no communication for almost 4 weeks - After multiple phone calls/follow up, came to know they are planning to fill the position internally - would appreciate if the management realize that they are wasting candidates time by calling for too many in-person interviews - surprising they did not know they had a internal candidate for this position - before they opened up job posting/interviews etc
