I applied through a recruiter. The process took 2 weeks. I interviewed at Brex (San Francisco, CA) in Dec 2018
Interview
Spoke with 1 recruiter and 1 engineer on the phone about my background. Then went on-site for the coding challenge. If that had gone well, you would later come in to meet the co-founders and director of engineering.
Interview questions [1]
Question 1
Implement a simple version of Brex’s backend (check if card has enough remaining balance to accept incoming transaction) using database. After that, think about fraud detection, if all you have is the information about the transaction.
