Evolent Front End Developer interview questions

First was technical test, completely based on javascript questions, like outputs, write programs , MCQs . Then they called for face to face technical interview. It was good. Interviewer asked some advanced concepts of javascript and to write the logics of some programs. On the same day, they shortlisted me for the next round. They had given one project assignment. I did exact same what they asked to do , but after 4 days I got a call that they did not get my assignment . I asked them to check it again, at that time they said, yeah we got it and will check the assignment. Again after two days, I got a call from different HR person that they didn’t get the assignment yet. I asked to confirm from the other HR, whom I sent the mail. After one week I mailed them for the confirmation and even tried to call them many times. One of them finally received my call and without asking my surname, she said you didn’t clear the round . I even mailed them for the clarification. They are just hopeless people from Evolent . They didn't share my feedback even asking so many times, atleast where code was wrong or not. It was just waste of time .
