Do you see any issue related to the size of the data, given in exam?

Answer: Not at all tasks you would be given with the huge data. But rather smaller dataset would be given. However, out of all the tasks couple of tasks would involve huge data. And that may become challenging and time consuming as well. Data may contain 100’s of parameters or columns in a csv file. You need to remove all the unwanted columns and apply join, filter and saving your final result. It is always recommended that all the easy questions should be attempted first and then go for high volume data. Because the cluster given to you most likely single node and not good enough for huge volume of the data.
