When you have radios you often find interference happening. As far as I am personally aware radio waves are the only waves that I am sure can interfere. If all EM apply do put it in that perspective in your answer. The thing that I can't wrap my head around is the fact that although the photons have no size and are just points, how can they overlap to interfere with another. It's like two entities in a game with no hitboxes colliding with each other.
It is not that radio waves are the only waves that can interfere. Other EM waves, such as lights, interfere too. Try to recall Newton's ring, and colors on a soap bubble from high school optics courses. Sound waves, water surface ripples interfere too.
To best understand EM wave interference, you think in waves, not in photons. If you definitely have to think in photons, think of "wave function of particles" and the statistical interpretation of wave function collapse, as people have done.
EM waves travel in the EM field which is a theoretical field that fills all space. Like waves in a pond they can overlap or superimpose or interfere or convolute or add together etc etc. its all the same terminology. Particles smash into one another and waves just pass each other by, example : 2 waves adding in collision will make a bigger wave only temporarily but then the waves will continue on travelling in each their own direction.
all EM waves are capable of interference. in the specific case of radio waves, the most convenient way to work with them is not by using the photon model, but instead the wave model. this is entirely appropriate for EM waves with long wavelengths and makes them easier to grasp and understand, especially when dealing with things like reflection off of objects (as in radar) and the effects of multipath transmission (as in radio transmission at 1 to 100 megahertz).
