I applied through a consulting firm and attended the process at the Hyderabad office.

It was a one-day event. The process was smooth, and the interviewer was cooperative. The focus was on basics.

1. Tell about the project.
2. Question on equals and ==.
3. Swap two numbers without using a third variable.
4. Write a program (WAP) to list the first 10 prime numbers.
5. Write a SQL query for the second-highest salary on the employee table.
6. Explain HashMap and WeakHashMap.
7. Explain the internal working of HashMap.
8. Explain why wait, notify, and notifyAll are in the Object class.
9. Analytical question: A man has 4 tablets – 2 red and 2 blue. The light goes on, and he needs to take 1 red and 1 blue tablet.
