Tortoise Energy interview questions

Applied for an summer internship position at the firm. First interview was with two candidates, and pretty casual. Technicals could be asked, but they didn't for me. I was invited to their superday at headquarters which started with a dinner the night before and a breakfast in the morning with the CEO. Three round interviews with breaks in between, an analyst shadow and an office tour. Fairly standard questions, nothing technical. Said I should hear back in 1-2 weeks, but never got a response back after that.
