Teradata interview questions

I got the call from recruiter for Pune Location. Ist round was technical. I have answered almost all the questions I have been asked from my project and the skills mentioned in my resume as well. But the interviewer was expecting answers and experience from other tools and technologies also in Big data. I was not able to answer a few and got rejected after first round. Also I was asked if I have completed any certification in Big Data Hadoop.

Three rounds were held. First round consisted of aptitude test and two coding problems. Second round was a technical interview and third one was a HR interview. Coding language was C/C++ and Java/Python.
