To prepare, focus on Spark's core concepts, including RDDs, DataFrames, and SparkSQL, and practice SQL queries for data transformations. Reviewing situational Spark questions, like handling large datasets or optimizing Spark jobs, will also be valuable.

I applied online. The process took 1 day. I interviewed at Nagarro in Jun 2022
Interview
Extremely condescending attitude from interviewer. His attitude made me feel uncomfortable. It seemed like he wanted to showcase his expertise in the field rather than conduct a fair interview. Answers were not valued, he questioned the things in my resume and passed on judgements for what he thought about it. Very bad experience.
