HR contacted me and scheduled the telephonic interview for a Bangalore office position. The interviewer called me and asked me to introduce myself, then gave his introduction. He asked a few basic Linux questions, where I missed one basic one, but the rest went well. Then he asked a medium-difficulty coding question, which I coded and solved the program in the most efficient way.

Three to four days later, I received a rejection email without any feedback or reasoning, which was unbelievable. I recently cracked the interviews of big names like Amazon and VMWare, as well as a few startups. Therefore, at the very least, they should have shared feedback. Very unprofessional.
