Growth Equity Interview - Prep Materials / Advice

I have an interview with a MM growth equity shop in a week and wanted to reach out to the community for help since it's been a while since a previous, similar thread has been posted. This would be very helpful to me and hopefully to other banker monkeys in the community trying to break into the industry.

A few specific questions: 1. How technical are growth equity interviews? Should it be expected that you'd be asked about LBOs (although not highly relevant)? 2. Investment pitch - assuming they'll ask for an investment pitch, how many companies should a candidate be prepared to talk about? Just one, or would they ask for a few ideas and rationale? 3. Mock phone interviews with CEOs (sourcing) - one of my coworkers interviewed at a growth equity shop and he had a mock call with a CEO (the partner acting as the CEO). What should you be trying to find out on a first call with a CEO? (solution suite, competitive positioning, relative size of business, go-to-market strategy, etc.) How would one go about asking these without being too blunt ("what is your revenue...")?

And finally, if anyone has any prep materials (case studies, interview questions, etc.) or general advice from previous interview experiences / their current roles, it'd be great if you could share your materials / experiences. Thanks in advance.
