Interview process was good. First round was written test. Most of the questions from Java and Hadoop. Second and Third rounds were technical. Most of the questions from Spark, Scala, Hadoop. If your basics are clear then you can answer them easily. Last round was managerial round where they asked about known technologies and salary expectations and all.

Even after these rounds they said me you did not clear interview process. I asked reason but they did not tell. So overall interview process was good but I could not figure out reason for rejection.

Most of the questions from Spark and Scala.
