Except they weren't. If a junior banker was placed on the Aramco deal team, that tells you they're well regarded. You don't put your C team on the Aramco deal. Furthermore, a client of this calibre brings together powerful people from across the firm and industry. The juniors will have had a chance to network with them. That's huge. (Not to mention, everyone at these firms gets paid salary, benefits and bonuses.)

I'm not harping on this to be mean. Downside management matters. That seems to have gone out the door around cryptocurrencies. These bankers made something if the deal failed and a lot more if it went through. Cryptocurrency investors had no such levers with which to manage downside risk (apart from limiting exposure). Savvy investors (and bankers) get rightfully suspicious at all-or-nothing propositions like the one cryptos collectively pitched.
