As a mentee, I would like to be able to search for mentor based on my time preference. With a lot of mentors from different parts of the world, I think for me it will be easier if there is a filter for time availability. For example, I live in Melbourne, Australia, so when I tried to look for a mentor, many of my favourite mentors are available at e.g. 2 AM or 4 AM and I only know their availability when I check their individual page. To reduce the steps of checking individual mentor page, I think it will be easier in the Explore page that a time preference filter is available.
