Epic Project Manager interview questions

An extremely long process with little to no communication. There are a lot of RED FLAGS that I came across while researching and going through the application process for them. Some include: emphasizing salary to overcompensate for work life, lack of communication, rude culture, training classes/programs that teach new hires how to demand results from other colleagues, etc. Also, the interview process seemed so unnecessary. why is it so long and why are there so many tests??
