I got selected through TNQT, the aptitude was quite easy (Be honest to yourself, have confidence and prepare regularly) normal speed, time, age, puzzle type question, English and coading was also there . In the coading section, they asked to convert binary to decimal. I received the mail after 14-15 days of the confirmation that I've cleared the test. I was called at the TCS office (pune) both HR and Technical rounds were taken together.
