Grammar tests, Hr rounds, Manager round. The whole interview went smooth. After 3 weeks, I get a call from the Hr about positive feedback for my interview and she said she will get back to me in 10 minutes. After that I haven't heard back from her. HIGHLY UNPROFESSIONAL behaviour. No response to follow-ups taken by me, after dropping a mail to the company, they reply saying that i am not shortlisted.

Was two stages. HR who asked basic swot analysis and values and plans etc. Editing team asked about education and grammar knowledge and also about why I want this job etc. This was asked by HR as well
