Circus Social 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.

What do you expect to gain from the work experience
