How many years of etl experience I had.
Write a query to check for duplicate records in database.
I got selected for both the technical rounds where the interviewer asked me about sorting algorithms, Normalization in database, few OS questions like diff b/w process and thread, about kernel, scheduling algorithms and Oops concepts (about abstract class, inheritance, encapsulation)
What was the last problem that you solved in your previous position? What is a problem and its solution that you are proud of?
SQL queries were very tricky. In some questions answers were given like a, b, c, d but the answers would not be from the above given options. They used to provide options to confuse you. Don't fall for that, think and then answer.
How do you keep track of all the various tasks at hand?
nothing they have asked
How many years of experience do you have on ETL
Tell me about a time when you <insert some undesirable situation, like making a bad decision on the job>, how you handled it, what you learned from it and how you'd handle a similar situation in the future.
