Pros
I had an excellent internship experience at Lucena. The Lucena team seems to be building something great in a very hot space (big data / machine learning), and the team was dedicated to accomplishing the tasks at hand. I found CEO Erez Katz and my coworkers to be intelligent and hardworking, but also kind and always willing to help, even when they were quite busy. Erez was a great leader and mentor to myself and others at the company. Lucena is working to build something that could revolutionize the financial industry, and Erez ensures the team is quite aware of this, contributed to a strong, tight-nit team culture. When I had an idea, the team supported me and was receptive - truly appreciated, especially as an intern early in my career. It was exciting to be part of this company and the fast-growing startup ecosystem in Atlanta.
Cons
Fast-paced environment with steep learning curve (par for the course for early stage start-ups). Employees sometimes had to do administrative tasks ourselves, though this may have improved as the company has grown.
