They usually don’t deliver on time and are too stressful to work with. It’s not worth it both personally and from a career perspective.

However if they manage to deliver a complex design on time, I’ll have lost a great career opportunity. It’s a gamble either way, but high complexity both in organization and design, usually yields a high failure rate on just about every metric I can think of except the metric of “I’m going to use this complex design to get another job and bail myself out of the dumpster fire I’m creating before I have to deliver anything of value”.
