Teradata interview questions

Recieved a call from recruiting team, scheduled a Technical Interview Round-1. Interviewers were friendly, but felt like they are not at all listening to the my answers. Expected it would take 1 hour as per schedule but they ended it in 45 mins. Mostly main focus was on C programming

The students who clear the written round are called for Technical Interview. To clear this round you should be clear with your basics. You should be prepared with Data structures and Algorithms and database. Students will be expected to write codes in the interview. They also ask questions from resume. You may be asked puzzles in this round.
