For trading internships do many firms give coding interviews? My understanding is that it is mostly maths, stats, probability and mental maths, but do many firms ask for coding as well? What about research internships?

What kind of questions can I expect from coding interviews? Will firms give interviews or take-home projects? I only ask because I don't see many people getting rejected after coding interviews, compared to after interviews testing the topics I mentioned before.

Should I be preparing seriously for coding interviews alongside maths interviews?
