Their HR interviewed me twice over call and then after month they reached out to me with an assignment of 6-7 long-length solution of PG Maths. I submitted the assignment on MS Word but they wanted it in MS LaTeX. So, I obliged and re-did it all. After submission they didn’t communicate to me the result for a 3 weeks. When I reached out to them they said that I failed to clear Quality Check and asked me to do another assignment. I refused. Never heard from them again.
