The Job Description which was given from the recruiter was including, Big Data Technologies like Hadoop, Spark, Map reduce, Python etc and some coding test. First round was horrible, the interviewer did not seem a technical person itself. He did not ask a single question related to Big Data. He was not interested in taking a coding test as well. He asked me to define a project which I worked on , when explained he did not ask any tech details.
