It was a real bad experience. I interviewed for the Pune location. The interview was conducted by a panel of two people. Both guys had good technical knowledge, but behaved in a very unprofessional manner. They laughed when I couldn't answer a few questions. They were passing comments among themselves, so it was more like a fun for them than an attempt to understand my technical skills. Even if you do not like my technical knowledge or answers, simply saying so is acceptable. However, laughing and implying that someone is worthless is not the right way to handle the situation.
Despite clearing the rounds, I declined to continue the process as these weren't the kind of people I wanted to work with.
**The same experience was shared by two more of my connections.
