Very bad interview experience at TechM. Even after waiting for more than 3 hrs, I didn't get a call for the first interview round. I was the first candidate to reach there and candidates who came after me was called for the 2-3 interview round. I get so pissed off by waiting for my turn and left the campus without giving the interview. Half of the day I have wasted there, very bad HR management. After waiting for for 2 hrs, I asked HR(Mr. Amar, I guess) about my turn, and he said he will check, but no reponse.
