Partner can’t hire me because of dry project pipeline

I am absolutely lost for words. I completed a final round interviews with a strategy firm recently and just found out via HR that, despite absolutely killing all the interviews, the partner can’t sign off on extending a job offer to me (and few other people they were planning to hire) because the department ( industry specific) doesn’t have enough projects and already a lot of staff on a bench. They also had a RFP fall through recently which made this situation even worse. They said they will keep me on the record and told me they will reach out again if circumstances change. HR mentioned, I won’t have to go through another round of interviews if this happens.

I’m genuinely feel so lost. This was my chance to break into strategy consulting from engineering consulting. Finally making it to the big leagues and have it all (the fancy job, target school, perfect pre-MBA background). This isn’t even about the money (I wasn’t going to make significantly more with this move) it’s more about not living up to the goals you set yourself. I worked so hard to get the experiences and opportunities I have now to even be considered by the big firms and now it all feels like I’m back to square one. I just want to cry, I’m currently on a remote client site and I dread the 5 hour drive back home knowing I was so close.
