Also it depends on the tip used for the soldering iron: those large surfaces have a lot more volume of metal that needs heating (plus you also need more volume of solder) so if one uses a conical tip it doesn’t transmit heat fast enough and you ended up with an irregular solder hill like that.

If you’re use to soldering smaller components, doing something like that is quite different and won’t come out as well until you get used to its peculiarities.

If you’re not at all used to soldering, that’s actually pretty good.

Totally agree on “works” being the gold standard, especially on a something like that which isn’t subject to significant mechanical forces (like, for example, a push switch would).
