I applied through a recruiter. The process took 2 weeks. I interviewed at PaymentWorks (Cambridge, MA) in Feb 2020
Interview
Rigorous and very similar to the likes of Google, Microsoft, etc.
Started with a 3 hour onsite with the director of engineering. Standard behavioral and whiteboard algorithm questions.
After passing this, I was asked to do a take home coding challenge to implement a REST client in any language of my choosing.
After submitting my solution, I was asked to do another 5 hour onsite with 3 additional interviews, mostly technical, with some more behavioral questions.
Interview questions [2]
Question 1
Given a stoplight at a 4-way intersection develop an algorithm to “optimize” the system. Justify and model variables you could optimize assuming a 4 way intersection.
I applied through a staffing agency. The process took 1 week. I interviewed at PaymentWorks (Waltham, MA) in Feb 2020
Interview
Initial meeting with VP of engineering, coding test, then final round interview with the team. VP of engineering was candid & genuine, and everyone made me feel very comfortable. The team here is really solid- great bunch of people! The logistics of the commute/hours don't work for me right now, but otherwise this seems like it would be a great team to work with, and a company with a lot of growth coming this year.
