I agree with @Jacob Miller and I would add that it is hard to link heavy finance/corporate topics to your personal experience.Yeah I agree with @FM302989 - I don't think there's a personal element to this.
If you're considering something from the perspective of a personal experience, it's really important to discuss something you've been materially involved in or affected by - attending a WD session as the 'origin story' for this may appear contrived.
There's definitely nothing to stop you discussing SPACs in other settings or different areas of the application, though!
I can give you an example, over the last few years I worked on the cladding safety in the UK. A very sensitive topic that resulted in a new Act and likely to make thousand of people bankrupt. I recently had to check if our apartment was affected too, it involved a lot of checks and a potential change in our mortgage terms. A lot of stress for a positive outcome.
So, I have linked a very important commercial issue with my own personal and professional experience.
