Astranis Software Engineer Controls and Simulation interview questions

7 interviews, 2 presentations and a take home project. About 30 hours total in interview time, working the project, and preparing for presentations. I thought that I did pretty well and was getting positive feedback, however after the entire process I was left with no offer, no explanation of why I wasn't chosen, and "it's impressive that you even made it this far". It's quite unfair that they expect a candidate to go through this entire process and then not help them out if they aren't selected with an explanation of why. Incredible waste of time with no constructive feedback to help me in my job search. Don't apply unless you're prepared to waste an entire work week of time.
