6-7 stages for a college placement cell call from quovatis Aptitude, coding, technical interview, Product manager interview, psychometric analysis, and Hiring manager interview. Each stage has its own way to evaluate interviewee. and Hardness is gradual.

After clearing test and first interview round i was put in the second interview round. I have never faced such an intimidating interviews theses days, they are still following old fashioned stress inducing interviews. I think their focus not to know the knowledge or the skillset of the candidate but to confuse and rattle him with weird scenarios or cases, with hard pitched tone. It was such a waste of time for either side but they would'nt have minded as it never looked to be a serious hiring process
