The interview process is archaic. They expect interviews with about 6 different people. Next, they expect you to review materials and take a test. Then, you have to take the time to prepare a presentation. Then you must ride along with others at least 1-2 times. If that were not enough, you have another final round of interviews. It's like the hiring process was created on a cave wall and managers have no power to decide without the input of 300 people. You'll have 40+ hours applying for a job you may or may not get. I removed myself from the process. 3-4 hours is reasonable, this interview process is not.
