Circus Social Machine Learning Engineer interview questions

3 rounds. 1st will be technical which includes English, Python, Aptitude. 2nd will be an assignment. 3rd is the manager round with HR. I cleared all and even sent my previous payslips and offer letter. They dint get back to me later. They knew my experience, my salary range, and expectation, when i had scheduled the interview after collecting all the documents they felt, am not fit to the position and wasted my time and also theirs. So lack of professional and roadmap.
