I had a interview at this organization. The HR was little confused in shortlisting my profile. Later I got a chance for the next round of the interview. I was getting hired for SEO Team lead.
I had an interview with a SEO Team leader and a SEO manager. Unfortunately, I was not hired just because I was not answerable to few critical and technical questions.
My point is that after gaining years of experience in organizations there's not much value shown by employers if you're unable to answer few definitions of technical terms. However, a very few organizations spend in learning and development programs for their employees.
Therefore, there is a huge gap in fitting an employee when recruiting according to their standard of recruitment levels. Only few organizations have L and D programs to train their employees perform better for their clients or customers.
Overall cracking an interview with proprofs is very tough. They ask typical and critical questions like what is syntax of robot.txt file, how will you research topics for 100 topics and 100 keywords etc. So be thoroughly prepared before attending an interview with them.
