RetailNext Project Manager interview questions

Literally the worst hiring process I've been through! Bad hiring process and hiring managers. They don't reply to emails, they make you wait forever, and they don't know what they want or talking about. I passed 2 rounds of interviews and got the home assessement, I spent 2 days working on it and it is solid (given I have experience in IoT with 16 years of experience in the field), I sent it to them, I wait for a month to get the denial automated email response. I didn't even know if they reviewed it and did not get a chance to present the work or understand their feedback as to why it is not suitable. I had the same experience 2 years ago when I applied for the same position with the same take-away assessement.
