what is your least favorite programming language?
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?
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)
