Infrastructure investment banking

Can provide a little bit of colour on this. 

Well for starters, it is a very technical group. You will probably be less focussed on qualitative work (as you might be in, say, tech) and more on the hard numbers. Modelling infra is very complex and usually done within the coverage group which has their pen on the model. Since revenue upside is usually capped via contracts such as Power Purchase Agreements (PPA), infra assets are levered up to insane levels, which means that the bankers have to evaluate downside risk very carefully. There is lots of debt sculpting and sensitivity analysis type work done there. 

I've seen some pitch decks in the space, and they tend to be quite dry but very very technical. The bankers in this space, at least at the bank whose pitch deck I saw, know stuff about infra inside out. If you don't enjoy building out costs curves and reading about natural gas pressurization, you probably won't enjoy this work too much. 

Seems infra bankers are gaining a stronger interest in infra verticals related to the green transition and data, and moving away from just railroads and oil pipelines.
