It’s a common way of hiring at many places. Perhaps they have already vetted your technical competence or they just don’t care and will mentor you. If you are an experienced developer you are already well prepared. Just be honest about your coding preferences and that there are many areas you deliberately avoid because they are outside your coding style or because they are bad form and you don’t waste time writing anti patterns. Sometimes the interviewer is inexperienced, for example cannot handle asynchronous logic without async/await, and they are mistaking preferences for competence. No amount of preparation will solve for their inexperience.
