A recent podcast I listened interviewed Kris Krohn and he actually recommended not for varying reasons.

that's a lot of bread to get the leads.. so you need tons of seed capital.those that have little to no marketing money to start .. pretty tough unless you bag a deal right out of the gate to keep you going.its the same for real estate agents getting started in that industry.. when  I had my shops and interviewed new licensed agents it was something we talked about.. you need ONE years of living expenses in the bank to even think about starting in this business.. same with wholesaling.. to try to do it with no money while it can be done .. flame out is virtually assured because of lack of capital in your small business. 

I'm currently in a Real Estate Investing course (through my college) and need to interview an experienced real estate investor for one of my assignments.

Plus I interviewed painters and bathroom remodelers and workers to upgrade our current home in order to get top dollar for the house.  

I heard a interview with Warren Buffet the other day.

interview a few and let them see past returns and tell them your plans and goals and it is usually an easy decision to pick one. 

You can interview property managers any day and see if you get the warm and fuzzy on them.

I'd reach out and interview several buyers  agents and see who has a track record of bringing great opportunities to their clients.

Even without having the highest offer.In most large multifamily transactions, the seller and broker will hold a round of interview calls with the top 3 to 4 buyers. 

Definitely make sure he's one of the lenders you interview and consider.
