it is ok, there is a writing test need to do. But overall it is normal. need to be confident, and not intimidated. I would say best to ask more on how the environment of the work place is.

There will be few stages of interview. First one would focus more on get to know you with HR. Then, you will be given an assessment and must submit on the time given. If you pass the assessment, then you will move to the last stage of interview which will be conducted physically at the office
