WorkMotion Software Engineer interview questions

It was 3 interviews, the first one was hr the second was technical and the third one was with my manager , the technical contained alot of questions and it was thorough

They requested a task related to state machines and gave me a deadline. After the submission they asked me to rate the difficulty and if i faved any problems. Then nothing! They just ghosted me and stopped replying and answering emails even though the outcome was very promising. At least have the professional courtesy to tell your candidates that they failed to meet your qualifications.
