We recommend to respect their religious views, everyday practice and habits as much as possible.
It is good idea to confirm it with the candidate first and if they can practice their religious habits during working hours or not.
For example, if a candidate who follows or practice Islam, the lunchtime in Japanese companies might overlap with their prayer times.
Please consider arranging space for the candidates with religious views to do their prayers. Prayer times also depend on each person and they would prioritize these practices over any other work-related tasks. It is very important to confirm these with both sides if it is feasible.
