The interview was scheduled in 3 stages. 1st screening round- Basically they want to test the domain knowledge. The job roles yoh have applied for. Not very tough question but question from all over domains. I was asked 2, 2 questions from SQL, SCALA/Python, Spark. SQL- Simple GroupBy questions Spark- Basic aggregation functions Python- find even number Other questions from spark/ command line/ aws/ Apache DAG etc. Round 2: I was not expecting the interviewer to ask me questions like syntax of spark-submit, UDF etc. The interviewer was not audible at all, I was getting a lot of voice breaks from the interviewer and also his accent was not very clear. I had a tough time in understanding what he wants to ask. The questions was also very unexpected. How do you connect Spark with oracle/ hive etc. give the syntax. I was like who asks these questions in the world of Genrative AI. But still he sticks to it and keeps on asking questions like these. Below are the questions: Types of join in SQL, How will you connect Spark with different databases write syntax for it. How will you connect AWS S3 with spark. How will you remove/ show the duplicates from a table (spark, sql) UDF in spark and its syntax. Spark-submit syntax How to create table in hive.
