Tata Consultancy Services Data Engineer interview questions

Interviewer was not interested to take Interview. Joine 15 minutes late. Then didn't allow to update project or even introduction. Specifically pointed out thoses cloud services that were not part of CV and ended the interview.

telephonic interview: it started with a normal introduction then slowly questions were from Pyspark, optimisation techniques, caching, etc. What i observed was questions were not and confusing at the same time.
