It's interesting that you're asking by using an example that came out around the time you started learning production. I started in 2012 myself, and I finished my first composition in Reason around the time Loreen's Euphoria featured in Eurovision, so I knew that's the year it was from.
I feel there are big factors that can make a difference to the answer for your question, including knowledge of music and/or audio before starting production learning, and how much time and money you spend on it. Equipment can make a big difference. It might seem hard to program certain sounds, but then you might buy a synth that has something just like that straight out of the box. One thing that has helped me a lot so far was to deliberately spend 6 hours of production time on 4 bars of music to see what I could do with it. I spent it experimenting with layering of different sounds and effects. It gave me the confidence that I really could produce the sounds I was seeking, and that it's worth spending a lot of time finding or programming those sounds.
Here's Zedd mentioning an example of sounds taking a really long time to choose:
And I think this is the "post-drop" section he might be talking about (until 2:16):
Here's Skrillex and Justin Bieber talking about it (until 4:27):
I think it's worth knowing that producers spend a lot of time on sounds.
