Teradata Developer interview questions

Three Telephonic rounds and then final HR round through Skype. Overall process took around 20 days and finally offer was released. Interview process was bit difficult as they completely about Teradata covering all the possible bases.

Interview process was ok. They took 2 weeks to offer me. I am on H1b, so they have to transfer my H1b visa. First they told me it will take 4-6 weeks of time to transfer the visa. Due to miscommunication between HR and Legal Team they started my H1b Transfer after 5 weeks. Still it is more then 17 weeks they are still working on transfer. Teradata process is very slow. Their HR is unresponsive.
