My immediate HR contact was pretty helpful - working on Sundays and & 7 ams. Around 2-3 rounds, however, my last round was daunting - which was supposed to be a normal round but it quite wasn't as it was with the Head HR and he technically threatened me. He wanted a verbal assurance that I will definitely join though the next sentence that came out of his mouth literally quoting "The industry is very small, the city is very small, our paths might someday cross just in case you decide otherwise" and I was completely shaken by such a remark and decided not to pursue this company.
