2 month interview process

Ive been interviewing for a big footwear company since February. I have made it through all three interviews but the process has been super slow.

Does anyone know why this is taking so long? I honestly don’t understand. This is the first time it has happened to me. Either way I did get a response this week saying they will trying to have a final answer this week but it’s already Friday.

Not sure what else to do but keep applying to other jobs.
