trivago Project Manager interview questions

Terrible interview process. No human interaction in the first 2 rounds. 1st round was asked to record 3 minute videos each for 10 questions and upload. Then sent a case study to work and upload. No reply for 3-4 weeks and then sends a generic email that solution was not detailed enough. It looks like my presentation was not detailed enough for the company to pick up implement it directly without hiring for the role you posted?
