Yesterday during the GO Rocket event, I had something annoying. Not knowing the composition of an opponent before going in meant I could wipe only because I came in with a few water types only to face a Venosaur.
So is there a way to know what you'll be facing before going into a fight with GO Rocket?

The "taunt" line that the grunt says (right when you're confirming your team) will hint at the general makeup of the grunt's team--particularly the third Pokemon.
Source 1, source 2 (credit to Wondercricket), plus hints as to good compositions to bring.
