Indeavor interview questions

The process was regular 1) call with 3 people with common questions. Asked about salary expectations in the end. 2) Decided to move forward with tech task which was time deadline a week. 3)Task was successful - decided to proceed with 2 managers 4) Told during /after a week will be a response . No response! After 9 days texted myself to know - and in a day got decline without any normal reason. My opinion was the following: the company needs are cheap employee. I asked higher salary than they pay in Greece but normal for such responsibilities. Impression is negative because they knew my expectations and they proceeded with me as it took me 2 weeks in total to be done with the task and preparation to launch the task (project). As for me it is not honest behaviour.
