Usually, an interview has a couple of rounds, followed by a customer round.

The first round was either a telephonic or face-to-face interview, which contained questions related to the job description. They also looked for your approach to solving a problem, given an example.

In the second round, I was given a couple of Java problems and asked to code. They looked more for problem-solving and analytical skills rather than just knowing the answer.

Hope this helps!

There were no difficult questions, just asked to code a couple of programs.
