I applied through an employee referral. I interviewed at Vertica (Boston, MA) in Jun 2019
Interview
1. Initial phone screen with general behavioral questions
2. Coding challenge sent over email to be completed in Java, Python, or C++

Interview questions [1]
Question 1
For the coding challenge they sent a program to be debugged so it would run faster. Find the most expensive computations in the program and optimize.
The interviews were a System design interview And a discussion about the Vertica architecture. They also gave a take home assignment. Overall very positive interview and very interesting interview topics
