Lateral Interview Advice Needed

I'll be honest, I think key figures are less important than knowing why the deal was done and what your contributions to the deal were.

When they ask you to walk them through a deal, I'd give them a high-level overview of the few deals I'm most comfortable with, then offer to walk through my favourite but say they can ask about any of them. Then, I would probably dive into the rationale, the process itself (to the ability I can), and what I contributed through each part. For example:

"In x file, the company came to us after their share price had precipitously declined out of fear that an activist shareholder may try to capitalize on their weak position. With that, we launched a strategic review which necessitated that we start work on company positioning materials and begin to plan outreach as part of the review. During this phase of the process, I was primarily responsible for the 80-page CIM and consequently the Teaser, I drafted outreach e-mails to prospective counterparties, and I coordinated with the client to organize the VDR. Once we launched the first phase of the process, I coordinated meetings with counterparties, exchanged partially-signed NDAs, granted counterparties access to the VDR, and facilitated buyer due diligence. We are now in the second phase of the process, which I can't speak too openly about, but I continue to facilitate buyer due diligence at a deeper level and act as an intermediary between key counterparties and management."

Something like that. I'd make sure my other experiences touch on stuff I didn't do in x file - e.g., in file y, I've been primarily responsible for the LBO model, so I would say in this file I'm really getting my hands dirty in a technical sense. While this is not as progressed as x, I've been able to advance the model to a place where my VP feels it is useable as a "banker model" for the pro forma company.
