MM PE Interview First Round Call

Hey guys, my boss hooked me up with this small MM shop in New Jersey and I'm gonna have a call today at 4PM. I currently work in a sort of corp dev role for a large company and thus my questions are around how to spin my background into something that looks competitive compared to a kid who worked in ibanking for 2-3 years and has all the technicals down pat.

Unfortunately it was supposed to be a buy-side position I joined in but since I joined 2 years ago we did not close any buy side transactions and instead I've been on some sell-side processes that did close but weren't technically intensive. My modeling skills are pretty lacking because of this.

My job is mostly process-oriented, making sure timelines were met and more "looking over the shoulder" of the bankers we engaged to see how they view modeling instead of being the analyst on the ground running the show. It was also mostly internal work creating 1-2 page PPTs explaining an acquisition opportunity at a high level.

I guess my question are: Will this call be technical in any way or is it mostly fit and story? And then how would you best frame my story to at least make it into an in-person interview where I can get rekt by some case study requiring me to churn out an LBO in 15 mins?
