As usual there's an initial interview with HR. Then depending on the job applied there will be some kind of practical test. In the case of being an analyst, I was instructed to make a brief report about a certain industry in a specified geography. There may or may not have a presentation of your work. Afterwards, if they like your work, you'll proceed to another interview with the hiring manager, and if things work out, possibly another interview with a higher-up (which is usually the final interview). I would advise to keep relaxed but stay grounded, do your research, prep in advance, and you'll do fine. Emphasize how your skills fit with the requirements of the post.
