I applied through university. The process took 2 weeks. I interviewed at Reinventing Geospatial (Blacksburg, VA) in Feb 2017
Interview
The interview primarily consisted of coding-related questions including the fundamentals of object-oriented programming (abstraction, encapsulation, & modularity). Since the Summer internships at RGI tend to have a lot of competition, so good luck.
Interview questions [1]
Question 1
They wanted to know if I had some understanding of data structures, namely list-based data structures and included one tree traversal question.
